BER for BPSK in ISI channel with MMSE equalization

by Krishna Sankar on January 24, 2010

BER plot for BPSK in a 3 tap ISI channel with MMSE equalizer

In the past, we had discussed BER for BPSK in flat fading Rayleigh channel and BER for BPSK in a frequency selective channel using Zero Forcing Equalization. In this post, lets discuss a frequency selective [...]

MIMO with MMSE SIC and optimal ordering

by Krishna Sankar on December 6, 2008

2x2 MIMO MMSE-SIC equalization

This post attempts to build further on the MIMO equalization schemes which we have discussed – (a) Minimum Mean Square Error (MMSE) equalization, (b) Zero Forcing equalization with Successive Interference Cancellation (ZF-SIC) and (c) ZF-SIC [...]

MIMO with MMSE equalizer

by Krishna Sankar on November 2, 2008

BER plot for 2x2 MIMO with MMSE equalization for BPSK in Rayleigh channel

In a previous post, we had discussed a 2×2 MIMO transmission using BPSK modulation in Rayleigh channel with a Zero Forcing equalizer. The simulated results with the 2×2 MIMO system  with zero forcing equalizer showed [...]
