QUASI-ORTHOGONAL SPACE-TIME BLOCK ENCODER, DECODER AND METHODS FOR SPACE-TIME ENCODING AND DECODING ORTHOGONAL FREQUENCY DIVISION MULTIPLEXED SIGNALS IN A MULTIPLE-INPUT MULTIPLE-OUTPUT SYSTEM

摘要

Embodiments of a quasi-orthogonal space-time encoder, decoder and method for space-time encoding and decoding of orthogonal frequency division multiplexing (OFDM) signals in a multiple input multiple output (MIMO) system are described herein generally. Other embodiments may be described and claimed. In some embodiments, a method of decoding received multicarrier signals includes deriving objective functions from a received signal matrix, minimizing objective functions to produce decoded hard bits, and decoded soft bits. Solving the simultaneous linear equations of the objective functions to produce. ; MIMO, OFDM, Objective Function, Quasi-Ortho, Hard Bit, Soft Bit
