Latest Patents

Jose Marcelo Lima Duarte holds a patent for a "Full search MIMO detector for recovering single or multiple data stream in a multiple antenna receiver." This invention presents an optimum form of maximum likelihood MIMO detector, known as the SFS ML Detector. It computes the Log-Likelihood Ratio (LLR) of the most likely received bit sequence from the received signal, which consists of multiple signal streams from a MIMO channel and an estimate of the channel. The process involves five simple steps: QR factorization, computation of partial Euclidean distance, sorting of the partial Euclidean distance, selection of surviving hypotheses through algorithmic rules, and computation of the maximum likelihood from the surviving full Euclidean distance. This method significantly reduces the number of computations and comparisons required compared to the theoretical maximum likelihood detector, without sacrificing performance.
