In this paper, an asynchronous cooperative cellular system is investigated on the uplink. We propose a signal detector which involves successive interference cancellation (SIC) and parallel interference cancellation (PIC) to suppress the impact of interference caused by co-channel users and imperfect synchronisation. Simulation results show that the proposed scheme provides significant performance...
Cooperative communication is a promising technique that uses many relaying nodes to combat channel fading. To achieve better communication and lower computational cost, some relays in good condition should be selected from all available relays. However, the original algorithm to select m' relays from m relays will need to compute C( m, m' )times, which has high complexity. In this paper, two lower...
The uplink capacity of cellular systems, where the co-channel interference (CCI) limits the system capacity more than thermal noise, is investigated in this paper. We evaluate the overall system capacity under slow fading when space-time block codes (STBC) are employed. A power control technique suited for STBC is proposed to improve the bit error rate (BER) performance on the target link and the...
