This paper presents a novel decoupling technique between two closely spaced MIMO antennas whose edge to edge spacing is0.03λ (1.975mm).A microstrip resonator is used in between the antennas that act as a decoupled device. The MIMO plays an important role in the current communication system due to its enhanced data transferring rate. However, the closely spaced MIMO antennas have a major disadvantage of high mutual coupling (MC). MC affects the entire characteristics of MIMO antennas and as a result, the performance of the antenna degrades. To overcome this problem, we have introduced a microstrip resonator that acts as an electrical wall between the MIMO antennas. The antenna has been simulated by using an IE3D EM simulator and a suppression of 48dB MC is achieved at a resonant frequency of 4.85 GHz. The MIMO antennas have been fabricated and the results are compared with the simulated ones. This antenna can be used in wireless communication, WLAN and satellite communication.

Multiple-input-multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) is a striking scheme, which has procured noteworthy importance as an auspicious contender for not only 4th generation but 5th generation wireless communication also. However, the mountainous problem regarding MIMO-OFDM is its considerably high peak to average power ratio (PAPR). In this literature, partial transmit sequence (PTS) mechanism is instigated on MIMO-OFDM system. Its effectiveness verification is displayed with assorted simulation results. Results reveals that PTS strategy not only refine but boost the potential of the MIMO-OFDM-based system, moreover, it has hitherto been indicated that with rise in sub-blocks, that are mostly non-overlapping, PAPR performance enhances. Further, the phase factors of MIMO-OFDM-based system are optimised by evolutionary techniques which drives its inspiration from galaxies called galaxy inspired swarm-based optimisation (GSO).

One of the major problems of today's TCP/IP network is the transmission system. If the bandwidth is full, we should use a new high-capacity transmission system. In the present paper, we put forward a method that besides the optimal use of available bandwidth, if the capacity is filled, the network will be automatically transferred to another network with higher bandwidth. In this regard, first design an adaptive PID controller to control the congestion for the existing network to get the most use of it. If the input data to the network is increased, more packets will be lost. Toward removing this problem through designing a supervisory and hybrid control system as well as considering the standard threshold limit for packets loss in each network, if this limit is exceeded, the existing network will be switched to a higher capacity network as it solves the problem of bandwidth and network quality.

In wireless communication systems, various performance metrics requires an evaluation of the Gaussian Q function. However, it is challenging to obtain a closed approximation to the Gaussian Q function in vicinity of small arguments. In this context, this paper portrays a tight approximation to the Gaussian Q function using the Gauss-Legendre numerical integration technique. This can be effectively used towards the computation of symbol error probability (SEP) integrals of different modulation techniques over fading channels. The framework provides an excellent agreement in contrast to the existing methods for SEP computation in Nakagami-m fading channels for all possible values of fading parameter. The model operates well for both higher and lower input arguments of the signal to noise ratios (SNRs). Furthermore, for performance evaluation in Nakagami-m fading channel, this approximation is used to derive the analytical solution for the SEP integrals in general rectangular and non-rectangular quadrature amplitude modulation (QAM).

In this paper, we propose a new fractional PIαDβ controller design to control chaotic systems. The controller design is based on the predictive control proposed by Yamamoto et al. (2001) and the fractional calculus. The parameters of the controller are determined by minimising the energy of the chaotic states using particle swarm optimisation. In order to obtain a simple model structure, we have used Takagi-Sugeno technique. A fractional PDβ and conventional predictive controllers have been also used as a comparative technique, in order to show the effectiveness of the proposed design one. The simulation results on Lorenz and Chen chaotic systems show the efficiency of the proposed fractional controller to reject disturbances and noises. These results show also that the fractional controller gives better results and overcome those of the fractional PDβ and conventional predictive controllers.

Passive sensing system, as the connection engine of the internet of things, changes the living environment and lifestyle of people profoundly. In order to improve the data transmission rate of passive sensing systems, this paper proposes and adopts scalable high-order backscatter modulation technology. While improving the overall throughput performance of the system, the problem of decoding difficulties caused by phase cancellation in the tag-to-tag communication process is solved. The practical problem of improving the throughput performance of the passive communication system in the system design at the expense of the bit error rate is solved. Finally, based on the probability distribution characteristics of the reflected signal, combined with the signal detection theory, an energy estimation strategy conforming to the environmental reflection signal is designed. The throughput performance and recognition efficiency of the passive sensing system are significantly improved.

Heterogeneous multi-core processors aim at overall performance improvement of computations for applications in the field of computing. It employs cores with varying capabilities to achieve high performance computation. This paper proposes a hybrid structure of CPU and FPGA (HCF) heterogeneous, hard and soft-core custom processor. Algorithms have been proposed for efficient utilisation of the proposed hybrid processor to work as a platform of work for the software demanding high speed and performance metrics. The evaluation for all the algorithm were carried out in zybo board belonging to zynq 7010 family of all programmable system on chip FPGA board, with Xilinx vivado 2014.4 as the development software.
