Abstract :
This paper examines the potential benefits of employing downlink feedforward transmit diversity (FF-TxD) in wireless systems which utilise adaptive modulation and coding. Instead of employing FF-TxD in such a system, the results presented suggest that multiple node B transmit antennas could better be utilised to implement a spatial processing technique which exploits parallelism in the MIMO channel, such as one of the space-time coding schemes.
