—Underwater acoustic channel usually has low data rate, long propagation delay, severe multipath effect, and time varying fading. Cooperative transmission is a new wireless commu...
—Recent information theoretic results on cooperation in cellular systems are reviewed, addressing both multicell processing (cooperation among base stations) and relaying (cooper...
Abstract— Consider the problem of base-station and subcarrier assignment on the downlink of a two-cell OFDMA system with adaptive modulation. The aim is to maximize a common data...
Abstract— In this paper, we analyze DS-CDMA/OFDM spectrum sharing system based on opportunistic spectrum access (OSA). In this system, the primary network air interface is based ...
