Mixed Phase-Precoding Method with Turbo Codes for Wireless-ISI Channel Applications

This paper presents a novel precoding method for BPSK signals through multipath fading channel. It is named as “mixed phase-precoding method”. This technique is developed mixing on the principle of spiral curve phase precoding and with a dimension partitioning technique. In order to apply this method for applications with turbo code, a specific detector is also proposed. Simulation results show that concatenation of turbo codes and mixed phase-precoding achieves a better gain compared to that of the ruled precoder method of spiral curve with the same turbo coding schemes.
