Performance Analysis of OFDM-SIMO Systems With Time-Domain Interleaving
This letter considers the performance analysis of orthogonal frequency division multiplexing (OFDM)-single-input multiple-output (SIMO) with time-domain interleaving (TDI) using zero-forcing (ZF) equalizers. The system instantaneous signal-to-noise ratio (SNR) is derived and used to evaluate the bit error rate (BER) and outage probability (OP) semi-analytically for various modulation schemes and number of receiving antennas. The obtained analytical results, corroborated by Monte Carlo simulation, show that the spatial diversity of the receiving antennas significantly impacts the noise amplification limitation inherent to TDI. Therefore, unlike the single-input single-output (SISO)-TDI with ZF equalization, the SIMO-TDI can provide significant gain over SIMO-OFDM. For example, the BER improvement of the TDI using two-antenna was about 7 dB when compared to OFDM with the same number of antennas, which is drastically different from the SISO scenario.
期刊介绍：
The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
