【简 介】:Abstract— We view the asynchronous random code-division
multiple-access (CDMA) channel as a time-varying convolutional
code. We study the case where the users encode their data, and,
therefore, the single user transmitters and the CDMA channel
appear as the concatenation of two coding systems. At the receiver
we employ serial Turbo decoding strategies. Unlike conventional
Turbo codes where both the inner and outer code may be selected,
in our case, the inner code is due to the CDMA channel which
we assume to be random. Nevertheless, the decoding system
resembles the decoder of a serial Turbo code and single-user
performance is obtained even for numbers of users approaching
the spreading code length.
Index Terms—Code-division multiple access, iterative methods,
random codes, Turbo codes.
