Abstract :
In this letter we show that a set of users with specified target signal-to-interference+noise-ratios (SINRs) are admissible in the uplink of a multicode CDMA system with multipath if and only if the sum of their effective bandwidths weighted by their corresponding number of codewords is less than the dimension of the signal space in which the users operate.
