Cyclic prefix based enhanced data recovery in OFDM
In this correspondence, we show how the cyclic prefix can be used to enhance the performance of an OFDM receiver. Specifically, we show how an OFDM symbol can be blindly detected using output symbol and associated cyclic prefix. The algorithm boils down to a nonlinear relationship involving the input and output data only that can be searched for the maximum likelihood (ML) estimate of the input.This relationship becomes much simpler in case of constant modulus (CM) data. We also propose iterative methods to reduce the computational complexity involved in the ML search of input for CM data.
