An effective way of reducing the energy consumption without affecting the quality of service is by adapting to the channel conditions. In this paper we describe one such scheme fo...
— Existing tone-reservation algorithms (such as the controlled clipper algorithm) for OFDM require a number of iterations to ensure the reduction of Peak-to-Average Power Ratio (...
We propose a wireless fading channel prediction algorithm for a pilot-symbol aided Orthogonal Frequency Division Multiplexing (OFDM) system. Assuming a doubly selective (time and ...
We proposed a novel interleaving technique, namely ada,ptive interleaving, which can break the bursty channel errors more effectively than traditional block interleaving. This new...
— In this paper, we investigate the adaptive resource allocation problem in multiuser multihop OFDM systems. Assuming that base station(BS) knows all channel information, we form...
