Abstract :
This paper extends and modifies MIMO QR algorithm to the frequency selective channel. A combining QR and PIC detection scheme was proposed. The performance of algorithm is evaluated based on computer simulation. Simulation results states that the performance of MIMO detection algorithms in frequency selective channel is better than the performance in narrowband channel, and the scheme has advantage over ZF-VBLAST in complexity and signal processing delay.
