Abstract :
An iterative RAKE receiver with semi-blind maximum a posteriori channel estimation for DS-CDMA systems is considered. The sensitivity of such a receiver to estimation errors in parameters such as Doppler spread, symbol energies and interference-plus-noise variance is investigated using simulations on UMTS/FDD assuming an ITU vehicular A channel model
