Latest Patents

Leclair holds a patent for a "Method for decoding linear space-time codes in a multiple-antenna wireless transmission system and decoder therefor." This invention presents an iterative method and a decoder designed to decode space-time codes in communication systems that utilize multiple transmission and reception antennas. The method strikes a balance between interference cancellation algorithms, such as BLAST, which can perform poorly in terms of error rates based on signal-to-noise ratios, and maximum likelihood algorithms, which, while optimal in performance, are complex to implement, such as the sphere decoder. The method involves a first matrix product between the received signal (Y) and a shaping matrix (B), along with a second matrix product between a subtraction matrix (D) and the vector of estimated symbols (S) from the previous iteration. The estimated symbols for the current iteration are generated by a subtractor that receives the results of the two matrix products. The matrix D plays a crucial role in subtracting the interference caused by other information symbols from the current information symbol S.
