The impact of channel estimation error on space-time block codes

We examine the impact of channel estimation error on the performance of 2 and 4 antenna space-time block codes. This is examined specifically in the context of space-time spreading as defined for the cdma2000 standard. The performance is determined by finding an expression for the probability of bit...

Zusammenfassung:We examine the impact of channel estimation error on the performance of 2 and 4 antenna space-time block codes. This is examined specifically in the context of space-time spreading as defined for the cdma2000 standard. The performance is determined by finding an expression for the probability of bit error when using BPSK or QPSK modulation and modeling the channel estimation error as a Gaussian random variable.
