Adaptive packet decoding in a wireless multiservice CDMA environment
Thomas Ketseoglou · 2002
In this paper, adaptive packet decoding in the form of code combining is applied in a certain wireless multiservice CDMA environment. Both voice and packet switched data are considered. The data services employ a slotted ALOHA-type of code division random access protocol. Concerning the channel and modulation, Nakagami fading takes place on BPSK, or on DBPSK modulated data. An analytically tractable and simple model based on the D and R/sub 0/ parameters is employed on the many to one link i.e. the reverse link in a wireless environment. Both queueing delay and channel delay analysis on data terminals are presented. It is shown that this system offers a high flexibility in accommodating multiple services with different traffic requirements.>
