The combination of error-correction with spread-spectrum is one of the important means to improve the performance of CDMA system
however
while coding gain is obtained
processing gain will decrease.In this paper
we discuss the coordination and trade-off between processing gain and coding gain when convolution code is applied to spread-spectrum CDMA system on condition that the total system bandwidth and information rate are fixed.
