Blind Detection of Psk Signals

چکیده
In this paper, a blind detection method is proposed to evaluate the information that can be drawn from the received phase shift keying (PSK) signals without channel knowledge at the receiver. First, we develop a method to determine the decision regions for detecting PSK symbols based on the maximum a posterior (MAP) criterion. Then, to reduce the numerical complexity, an approximated MAP criterion equivalent to a least squares criterion is derived. Numerical simulations are conducted to evaluate the performance of our proposed methods in terms of the mean squared error (MSE) and the bit error rate (BER).

We address the problem of blind recovery of multiple sources from their linear convolutive mixture with the cross-comelation and constant modulus algorithm. The steady state meansquared error of this algorithm is first derived to justify the proposal of a new cross-correlation and constant modulus type algorithm for PAM-PSK type non-constant modulus signals. Simulation studies are presented to ...

متن کاملA Simplified Constant Modulus Algorithm for Blind Recovery of MIMO QAM and PSK Signals: A Criterion with Convergence Analysis
The problem of blind recovery of QAM and PSK signals for multiple-input multiple-output (MIMO) communication systems is investigated. We propose a simplified version of the well-known constant modulus algorithm (CMA), named simplified CMA (SCMA). The SCMA cost function consists in projection of the MIMO equalizer outputs on one dimension (either real or imaginary part). A study of stationary po...
