## Abstract In this paper, we evaluate the theoretical expressions of the average coding rate, the probability of undetected errors and the probability of packet erasure (PE) of truncated Hybrid ARQ schemes with packet and code combining (CC) for direct sequence code division multiple access (DSโCD
Most CDMA systems serve only finite number of active users. Therefore, using Gaussian approximation to evaluate its performance is inappropriate. In such finite CDMA systems, the selection of spreading codes is of great importance because its performance is very much spreading-code-dependent. In thi
