摘要： Embodiments provide systems and methods for a novel multiple-input multiple-output (MIMO) equalization technique that produces a channel matrix that contains partly real coefficients and partly complex coefficients, referred to herein as a hybrid-MIMO equalization. MIMO detectors can exploit the hybrid-MIMO equalization to reduce complexity. Some embodiments provide systems and methods for equalizing a communication channel comprising receiving as an input a channel output vector, dividing the input into two vectors, a first vector that remains a complex number and a second vector that contains only real numbers, separating the second vector into its real and imaginary components, and regrouping the first and second vectors into a hybrid channel output vector that contains both real and complex coefficients.

摘要： A method and apparatus for detecting symbols in a Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (“MIMO-OFDM”) system. A MIMO-OFDM receiver includes a first detector that estimates a symbol of a first MIMO-OFDM sub-carrier and a second detector that estimates a symbol of a second MIMO-OFDM sub-carrier. The second detector differs in complexity from the first detector. A detector control block is coupled to the detectors. The detector control block assigns the first detector to process the first MIMO-OFDM sub-carrier and assigns the second detector to process the second MIMO-OFDM sub-carrier. The detector control block computes a list metric for a sub-carrier. Based on the list metric the detector control block assigns a candidate symbol list length to the detector processing the sub-carrier. Alternately, the detector control block assigns one of a variety of detector types to a sub-carrier based on the sub-carrier list metric.

摘要： Embodiments provide novel systems and methods for multiple-input multiple-output (MIMO) Max-Log detection. These systems and methods enable near-optimal performance with low complexity for a two-input two-output channel. Some embodiments comprise using a Max-Log detector to compute a set of log-likelihood ratio (LLR) values for a channel input by minimizing cost function while computing only one instance of the cost function for each value of each bit in a symbol. Other embodiments comprise using a Max-Log detector to compute a set of log-likelihood ratio (LLR) values for a channel input by computing all instances of a cost function for each value of each bit in a symbol and selecting the minimum cost from all computed instances of the cost function for each value of each bit.
