In various embedded system applications, the high speed multi-serial communication is necessary. Various embedded systems require DSP (Digital Signal Processing) to process information & FPGA to control the peripheral devices. UART (Universal Asynchronous Receive Transmit) is designed in FPGA & connected to DSP so as to meet the real time capability of system along with compact, stable & reliable data transmission. In this paper we propose a software-implementation technique of an UART to get a platform independent UART-core for high speed serial communication in FPGA. Here the core is written in Verilog & implemented using XILINX ISE.

This paper presents three models of Quadrature Amplitude Modulation (QAM) modem operating at data rate of 16.8kb/s to be transmitted over 32kb/s Adaptive Differential Pulse Code Modulation (ADPCM) channel. These modems operate at symbol rates of 2400, 2800, and 3360 baud with associated number of bits per symbol of 7, 6, and 5 respectively. The performance of ADPCM is studied considering these modems with different constellations. The simulation results show that the performance of ADPCM degrades as the symbol rate decreases or number of bits per symbol increases. Also, the performance with circular constellation is better than rectangular one.

It was proposed a method for the prediction of the occurrence of fourteen day resonances of gravitational tides in the Earth's crust. The data of registration of parameters of tidal gravitational factors including fluctuations of the barycenter in Earth-Moon system in different geophysical fields was presented for the first time. It was given the estimation of the amount of changes in the stress-strain state of the geological environment under the resonances influence. It was substantiated possible directions of using energy of the resonances of gravitational tides in the Earth's crust in oil and gas fields, the earthquake prediction, security of large man-made structures (hydroelectric dams), and the development of theories of single deformation killer waves.
