Abstract
In this paper, we are proposing a pilot-aided channel estimator for the multiple-input multiple-output (MIMO) directsequence code-division multiple access (DS-CDMA) communication systems based on the minimum mean-square error (MMSE) estimate of the attenuated transmitted signals in the presence of Rayleigh fading channel coupled with the white Gaussian noise. The proposed receiver consists of bank of matched filters matched to the signature waveform of the desired user followed by a nonlinear estimator, resulting from the MMSE estimate of the attenuated transmitted signal. Simulation results carried out for multiple values of signal to noise ratio (SNR) and number of users show that the theoretical predictions are very well substantiated.
