Abstract
Background & Objective: To analyze the performance of MIMO-OFDM system,
VBLAST detection suffers from computational complexity as well as high BER.
Methods: To improve the BER performance and to reduce the computational complexity of receiver,
we propose a modified VBLAST detection in MIMO-OFDM Systems.
Results: Simulation using MATLAB shows the improvement in computational complexity and in BER.
Conclusion: This modified VBLAST reduces the complexity of MIMO-OFDM System to 44.2% and
improvement in BER as compared to conventional VBLAST based MIMO-OFDM System.
Keywords:
MIMO, MMSE, OFDM, VBLAST, ZF, BER.
