Abstract
A wireless device with multiple antennae and configured to support orthogonal frequency-division multiplexed (OFDM), multiple-input multiple-output (MIMO) communications of a wireless local area network (LAN) over a wireless communication medium on a communication channel. The wireless device comprises: a MIMO demapper configured to receive a packet on the communication channel and to perform both linear together with non-linear decoding processes based on an initial communication channel estimate 'H', and with initial linear decoding of at least a first received symbol in a payload portion of the received packet followed by decoding of remaining symbols in the packet using non-linear sphere decoding, thereby reducing a level of complexity associated with non-linear decoding by extending a time interval available for an initial channel estimate decomposition portion of non-linear sphere decoding to span at least a portion of a n interval associated with linear decoding of at least the first received payload symbol.
