Abstract
Precoding is a technique that may be used in wireless communications when antenna spacing in a multiple-input multiple-output (MIMO) system is smaller than optimum spacing conditions. A precoding system and method are disclosed herein that distributes power among streams to trade-off increased data throughput and complexity of interference cancellation. Distributing power among streams may increase data throughput compared to singular value decomposition (SVD) precoding, but interference may be reduced compared to other methods that result in relatively high interference.
