This paper shows the effect of the system parameters for three previously proposed systems that depend on the principle of transmitting the data in blocks. The main idea for the first system is to move all the signal processing operations needed to eliminate the effect of the time variant channel from the receiver to the transmitter and leave the receiver quite simple (pre-coding). The other two systems make some sharing for the signal processing between the transmitter and the receiver in different ratios to obtain some enhancement on the performance of the pre-coding system.
