MIMO MMSE Decoder

Overview

System Overview

The MIMO Decoder accepts two independent input streams, and the channel estimation matrix as shown in Fig. 1. (For the full diagram please contact info@global-ipc.com) The inputs to the MIMO Decoder are the estimated channel matrix and the received vector of symbols. Since the transmitted symbols could be pre-coded, some processing may be needed (optional) at the beginning of the detection. The QR decomposition is performed in preparation for the K-Best decoding. The outputs of the QR decomposition and are fed to the K-Best decoder.
