Decoding linear space-time codes in multiple-antenna wireless transmission system, used in digital radio data distribution over local wireless network, uses matrices to remove interference caused by multiple propagation across ionosphere

摘要

The method consists of using a first matrix product between the received signal (Y) and a shaping matrix (B1), and a second matrix product between a subtraction matrix (D1) and the vector of the estimated symbols (S1-1) during the preceding iteration. The estimated symbols during the current iteration are generated by a subcontractor (9) receiving the results (r1,z1) of the two matrix products. The role of the matrix (D1) is to subtract from the current information symbol (S1) the interference caused by the other information symbols.
