| Abstract(in English) | This report presents a signal de-multiplexing scheme in branch metric calculation of soft decision decoding for a spatially multiplexed MIMO system. In a conventional MIMO system, de-multiplexing is carried out over the symbols received by multiple antenna elements and is separated from decoding. Therefore, the de-multiplexing requires multiple uncorrelated antenna elements in order to realize a full rank channel matrix. This leads to the limitation of the system capacity by the number of the receive antenna elements. Instead of splitting de-multiplexing and decoding, in this report, a de-multiplexing scheme combined in branch metric calculation in soft decision decoding is proposed. Based on ideal interleaving, independence among the coded symbols is assumed. The full rank channel matrix is formed as a candidate of the set of transmitted symbol sequences and the size of the matrix is equal to the transition path length for metric calculation in maximum likelihood detection. As an example of the proposed system, the performance of Trellis coded signal with maximum likelihood detection and soft decision trellis decoding on a Rayleigh fading channel is investigated. |
