The impact of transmission design and spatial correlation on the symbol error rate (SER) is analyzed for multi-antenna communication links. The receiver has perfect channel state information (CSI), while the transmitter has either statistical or no CSI. The transmission is based on orthogonal space-time block codes (OSTBCs) and linear precoding. The precoding strategy that minimizes the worst-case...
The symbol error performance of spatially correlated multi-antenna systems is analyzed herein. When the transmitter only has statistical channel information, the use of space-time block codes still permits spatial multiplexing and mitigation of fading. The statistical information can be used for precoding to optimize some quality measure. Herein, we analyze the performance in terms of the symbol error...
The degradation in the bit error probability of V-BLAST system is often owing to its low diversity and error propagation in the receiver. But if channel state information is available at the transmitter, we always design precoder to optimize the transceiver, in order to improve the performance obviously. In this paper, we firstly overview the ideal precoder with perfect channel state information (CSI)...
We consider a spectrum sharing based cognitive radio network where a secondary mulitple-input multiple-output (MIMO) communication link coexists with a primary user by opportunistically utilizing the transmit spectrum originally allocated to the primary user. The secondary link employs orthogonal space-time block coding (OSTBC) at the transmitter and maximum likelihood (ML) decoding at the receiver...
