Abstract

The effects of non-ideal channel estimation in multiple-input-multiple-output (MIMO) wireless communication systems using the eigenchannel technique for the independent symbol transmission are investigated in this paper. Analytical expression is derived for the Shannon capacity for arbitrary signal-to-noise ratio (SNR), training sequence length (TSL), transmit and receive antenna numbers. The weight error loss (WEL) that quantifies the increase in signal-to-noise ratio (SNR) required to meet a given capacity target due to weight jitter are investigated.
