Abstract— In many scenarios the commonly assumed symmetry in multiple relay channels is unrealistic. Therefore, this paper, through analytical and simulation efforts, investigate...
—In this paper, a user-aided adaptive TDMA (UAAT) algorithm is developed for real-time services to improve the system efficiency of OFDM based cellular networks. In the UAAT sche...
