Abstract

In this paper are described some new approaches to the definition of CDMA spreading functions. The simplest method increases the code space up to 50%. The most sophisticated one performs a very strong rejection to the delayed replicas of the interfering signals. Several advantages have also been found in the FFT implementation of PS-CDMA transmitters and receivers, the elimination of the analog matched filter being the most attractive one. Theoretical results have been supported by computer simulations, and comparisons with the traditional DS-CDMA design of spreading functions are also included.
