The equalization which confronts zero pre- fix OFDM systems and is improved

摘要

As for the system, the device or method of this invention, it is not complicated, but the quasi- optimum channel equalization technology for zero pre- fix orthogonal frequency division irregularity OFDM systems which maintain the efficiency of the smallest squaring equalization is offered. Technology of this invention rather than being needed by minimum mean squared error MMSE equalization improves equalization efficiency with degree of complicated it is low.
