3. Bounds on the maximum coding rate of multiple-access channels and feedback channels
Abstract : We provide upper and lower bounds on the coding rate of multiple-access channels (MACs) and feedback channels.Traditional MACs have been extensively studied under the assumption of availability of perfect channel state information (CSI).In Paper A we relax this assumption for a Rayleigh block-fading MAC and provide bounds on the sum-rate capacity.

4. Coding, Modulation and Multiuser Decoding for DS-CDMA Systems
Abstract : The general trend both in wireless and fixed network communication systems is flexibility in services, data rates, desired delay and performance. Future systems should not be designed for specific services but be more general and allow for a multitude of services, both now existing and those not yet invented. READ MORE
