- W175158152 abstract "This paper describes two blind algorithms for multicarrier code division multiple access (MC-CDMA) sys- tem equalization. In order to identify, blindly, the impulse response of two practical selective frequency fading chan- nels called broadband radio access network (BRAN A and BRAN E) normalized for MC-CDMA systems, we have used higher order cumulants (HOC) to build our algorithms. For that, we have focussed on the experimental channels to develop our blind algorithms able to simulate the measured data with high accuracy. The simulation results in noisy environment and for different signal to noise ratio (SNR) demonstrate that the proposed algorithms are able to estimate the impulse re- sponse of these channels blindly (i.e., without any informa- tion about the input), except that the input excitation is i.i.d. (identically and independent distributed) and non-Gaussian. In the part of MC-CDMA, we use the zero forcing and the minimum mean square error equalizers to perform our algo- rithms. The simulation results demonstrate the effectiveness of the proposed algorithms." @default.
