Abstract :
In the multiinput multioutput (MIMO) wireless communication system, especially in the V-BLAST, the received signal vectors detection is the crucial part that impacts the system performance. This paper introduces a new V-BLAST detector that can gain more diversity gain. This detector utilizes the successive interference canceling (SIC) and parallel interference canceling (PIC), during the iteration of SIC and PIC, turbo code is used to guarantee the reliability of PIC. Compared with other detection algorithm, this new iterative detector can enhance the receive diversity. This paper simulates the algorithm with OFDM modulation under multipath Rayleigh MIMO channel. From the simulation results, the system performance can be improved and the complexity of this iterative detector is very low.
