Abstract
The performance of a DS-CDMA system using coherent receivers with the despreading sequences weighted by adjustable chip waveforms is present ed. A new expression for the signal to interference plus noise ratio ( SINR) of the decision variable is derived for the proposed receiver. W hen the system parameters are given, the derived SINR expression is de termined only by one parameter of the weighted despreading sequence. A s a result; the parameter can be simply tuned in practice for multiple access interference (MAI) rejection.
