Abstract :
High signal-to-noise ratio (SNR) performance of the blind minimum output energy (MOE) receiver and the Capon channel estimation technique are analyzed in the large code division multiple access (CDMA) network where both the spreading factor and number of users go to infinity with the same rate. Upper and lower bounds on the signal-to-interference-plus-noise ratio (SINR), efficiency and asymptotic efficiency of the MOE receiver are derived and compared with those for the optimum minimum mean squared error (MMSE) receiver.
