Latest Patents

Chen's latest patents include innovative methods for detecting spatially multiplexed signals in over-determined MIMO systems. One of his notable inventions is a method and apparatus for obtaining better detection performance by improving the matrix condition for an M×N over-determined MIMO system. This invention enhances the condition of a matrix to be inverted for solving various detection problems by reordering equations of the original MIMO system. The result is a reordered channel matrix and received signal vector, ensuring that the top N×N sub-matrix has the largest determinant among all possible sub-matrices. This method allows for a more accurate estimate of the transmit data bits. Another significant patent involves a single-stream sliced maximum likelihood aided successive interference cancellation method. This method estimates spatial signatures of both signal and interference data streams, forming a composite channel matrix. It performs QR decomposition of the channel matrix with different spatial orderings and selects the stream with the largest post-detection signal-to-interference-plus-noise ratio (SINR). The strongest stream is demodulated using the single-stream sliced maximum likelihood method, while the remaining weaker streams are processed using a low-complexity MMSE method.
