—In this paper we present an analytical approach to evaluate the M-QAM bit error rate and carrier frequency dependent throughput of OFDM systems subject to various receiver impai...
— In an OFDM system, channel estimation can be considered as sampling the time-frequency response of the channel through a number of known pilot symbols placed across the time-fr...
—In this paper we present an analytical approach to evaluate the M-QAM bit error rate (BER) as well as channel capacity of Alamouti space time coded OFDM systems in case of direc...
—In this paper we present a study on pilot aided time and frequency synchronization for Opportunistic Radio (OR) OFDM systems which apply adaptive subcarrier allocation technique...
This paper proposes a pilot-aided joint channel estimation and synchronization scheme for burst-mode orthogonal frequency division multiplexing (OFDM) systems. The scheme eliminate...
