TLDR
In some radio communication systems where the overall interleaving delay that can be tolerated by a user is limited, it is found that channel coding may not be practical from the viewpoint of spectrum efficiency.Abstract:
The authors discuss and characterize factors affecting the use of error-correcting codes with bit interleaving for a channel model which includes antenna diversity in interference-limited fading radio environments. The coding gain required to compensate for the bandwidth expansion due to channel coding is investigated for binary phase-shift keying (BPSK) with coherent and with differential detection, and for orthogonal signaling with noncoherent detection. In some radio communication systems where the overall interleaving delay that can be tolerated by a user is limited, it is found that channel coding may not be practical from the viewpoint of spectrum efficiency. >read more

Signal and interference statistics of a CDMA system with feedback power control. II
S. Ariyavisitakul,Li Fung Chang +1 more
TL;DR: A combination of discrete-event link simulation and analysis of the obtained SIR statistics is used to explore the previously little-known behavior of a CDMA system using SIR-based power control and to obtain performance estimates for such a system under various operating assumptions.

Signal and interference statistics of a CDMA system with feedback power control
S. Ariyavisitakul,L.F. Chang +1 more
TL;DR: A feedback power control approach that allows power commands to be updated at a higher rate than the rate of multipath fading is investigated and it is shown that often-used analyses based on perfect average power control lead to optimistic capacity results.
