—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...
Abstract--Physical transceiver implementations for multipleinput multiple-output (MIMO) wireless communication systems suffer from transmit-RF (Tx-RF) impairments. In this paper, w...
Orthogonal-frequency-divisionmultiplexing(OFDM) transforms a frequency-selective multiple-input multiple-output (MIMO) fading channel into a MIMO-OFDM channel that has a well-defin...
— We propose an open-loop two-dimensional linear pre-transformed (2DLPT) multiple-input multipleoutput (MIMO) orthogonal frequency division multiplexing (OFDM) system. The nT N Ã...
