    Abstract

    In this paper, we propose a new broadband singlecarrier (SC) multiple-input multiple-output (MIMO) transmission method to reduce the residual inter-antenna interference (IAI) and inter-symbol interference (ISI) after the minimum mean square error based receive filtering (Rx MMSE filtering). The proposed method jointly performs transmit and receive MMSE filtering (joint Tx/Rx MMSE filtering) to transform the MIMO channel to the orthogonal eigenmodes and allocate the transmit power based on MMSE criterion. Also, as the received signal-to-interference plus noise power ratio (SINR) of each eigenmode is significantly different, rank adaptation and adaptive modulation are jointly introduced to narrow the received SINR gap between each eigenmode. The superiority of the proposed method (adaptive SC-MIMO transmission using joint Tx/Rx MMSE filtering) is confirmed by computer simulation.
