Impact of Fading Correlation, Polarization Coupling and Keyholes on Mimo Detectors for V-blast Architecture
نویسنده
چکیده
This paper analyzes the impact of fading correlation, cross polarization coupling and channel degeneracy alias keyhole condition on the error performance of V-BLAST MIMO system that employs detector algorithms like ZF, MMSE and ML with ordering and successive cancellation. Deleterious impact of above mentioned channel impairments on MIMO system capacity is studied. Simulation results show the BER performance of these detectors for different modulation schemes. It is observed that lesser the channel fading correlation and cross polarization coupling values better is the performance of these detectors. Study is extended to see the effect of transmit and receive antenna correlation on Ergodic MIMO capacity.

The rich-scattering wireless channel is capable of huge theoretical capacities. The multiple input multiple output (MIMO) antenna system provides very promising gain in capacity without increasing the use of spectrum, throughput, and power consumption. This is also less sensitivity to fading, hence leading to a breakthrough in the data rate of wireless communication systems. There are many sche...

In this thesis, we evaluate the performance of multiuser detectors over an uplink using AWGN, Rayleigh flat fading single-input single-output (SISO) and multiple-input multiple-output (MIMO) channel models. First, we review the performance of three multiuser receivers; the decorrelator, the MMSE receiver and the multistage parallel interference cancellation receiver in an AWGN and Rayleigh flat...
