In this paper, a new signal detection scheme using both parallel interference cancellation (PIC) and equalization for the efficient joint distributed space-time coding is proposed to suppress the impact of imperfect synchronisation in distributed cellular systems. Simulation results show that the proposed scheme outperforms the existing joint DSTBC decoded scheme in terms of BER. And also it achieves...
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...
In this paper, we study the joint optimization problem on channel coding, power allocation, and route planning in wireless sensor networks (WSN) using dynamic programming (DP). Each sensor node has multiple antennas and applies orthogonal space time block codes (OSTBC) in order to improve the transmission reliability. A decode-and-forward protocol is adopted to relay the signals. The objective function...
In this paper, we propose a detection and decoding scheme for a MIMO system using space-time codes (STBC) with external interferences. It is known that current cellular systems are limited by co-channel interference (CCI) more than thermal noise. However, traditional linear decoding schemes have rather poor performance in decoding STBC in this interference-limited environment. To achieve good BER...
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...
