Abstract:
ABSTRACT In this paper, we present a systematic study of the subspace-based blind channel estimation and equalization method. We first formulate a general signal model of multiple simultaneous signals transmitted through a channels, which can be applied to a modern digital communication systems QAM. Based on this model, we then propose a generalized subspace-based channel estimator by minimizing a novel cost function. We investigate the asymptotic performance of the proposed estimator, i.e. bias, mean square error (MSE), NRMSE and also estimate the channel performance Keywords:- OFDM, semi-blind, space-time coding, subspace based channel estimation.
