Adaptive Transmit Diversity and Spatial Multiplexing for MIMO-OFDM Systems
نویسندگان
چکیده
Space-time block coding (STBC) and Spatial multiplexing (SM) or BLAST (Bell Labs Layered Space-Time) are promise approaches that exploit the MIMO channel to provide higher data rates and diversity gains with no sacrifice in bandwidth. In this work, we present a hybrid MIMO scheme that combines transmit diversity and spatial multiplexing. The proposed scheme can achieve arbitrary number of multiplexing rate.

The MIMO system can meet the growing demand for higher capacity in wireless communication fields. So far, the authors have reported that, based on channel measurements, uncoded performance of narrowband MIMO spatial multiplexing in indoor line-of-sight (LOS) environments generally outperforms that in non-LOS (NLOS) ones under the same transmit power condition. In space-frequency coded MIMO-OFDM...

In this letter, we propose a multi-cell cooperation method for broadcast packet transmission in the OFDM-based cellular system with multiple transmit antennas. In the proposed method, to transmit two streams of spatially demultiplexed or transmit diversity coded symbols, we divide a coded packet into subparts to each of which different cell group and antenna pairs are assigned. It is shown that...
