Performance of array signal processing algorithms for wideband digital wireless communication

We consider several array signal processing architectures equipped with different training approaches and evaluate their performance in high-speed digital wireless transmission by way of computer simulation. The array architectures considered are: space-only, delay-combine, and multi-stage space-time. The training approaches considered include max-SINR, LS (least-squares) with channel estimation, and LS without channel estimation. These arrays are simpler than the full space-time architecture at the cost of a lower error-rate performance.
