Abstract

In this paper, we propose a joint transmit and receive filtering based on minimum mean square error criterion (joint Tx/Rx MMSE filtering) and joint rank adaptation/adaptive modulation for single-carrier (SC) multiple-input multiple-output (MIMO) packet transmission. Joint Tx/Rx MMSE filtering transforms the MIMO channel to the orthogonal eigenmodes to avoid the inter-antenna interference (IAI) and allocates the transmit power based on MMSE criterion to sufficiently suppress the inter-symbol interference (ISI). Joint rank adaptation/adaptive modulation narrows the received signal-to-interference plus noise power ratio (SINR) gap between eigenmodes. The superiority of the SC-MIMO packet transmission using joint Tx/Rx MMSE filtering and joint rank adaptation/adaptive modulation is confirmed by computer simulation.
