Abstract
Various aspects of a system for an adaptive VBLAST receiver for wireless MIMO detection may comprise utilizing log likelihood ratios (LLR) to selectively cancel interference in a received signal when information contained in one or more layers is encoded. Following the selective cancellation of interference, further computations may be performed on the residual received signal. Various aspects of the invention may comprise a linear detector with improved performance in comparison to some conventional VBLAST receivers. Performance may be measured by, for example, a packet error rate (PER) for a given signal to noise ratio (SNR) associated with the received signal.
