ABSTRACT
Wireless communication is being used for many purposes and has become very frequently used mode of
communication. Blind equalization methods are being used to estimate the received signal without the necessity to
use the trained sequences in the input. Many methods CMA (Constant Modulus Algorithm), FS-CMA
(Fractionally spaced CMA), PC-CMA(Phase compensation CMA), MMA(Multi-Modulus Algorithms) are being
used for blind equalization. However all the methods are affected due to Inter symbol interference (ISI) and Bit
error rate(BER) in the transmission.It has been proved [9] that CMA performs reasonably well compared to LMS
methods in the absence of trained sequences. However the method suffers from issues such as Partial spacing,
non-phase compensation etc.
In this paper the performance evaluation of FS-CMA in comparison to CMA considering the model parameters at
which the maximum performance can be achieved is presented. The performance of FS-CMA as against CMA in
respect toInter Symbol interference ISI[1] and Bit error rate (BER), considering optimum parameters has also
been presentedin this paper.
