This paper deals with the performance analysis (i.e., Symbol Error Rate) of M-ary Phase-shift-keying (M-PSK) and M-ary Quadrature Amplitude Modulation (M-QAM) to transmit information using Selection Combining (SC) diversity technique over flat Rayleigh communication channel with Orthogonal Frequency Division Multiplexing (OFDM). It is well known that the multipath fading phenomenon is an inherent...
In this paper we investigate the performance of IEEE 802.16-2005 OFDMA system with high order QAM/QPSK mapping in the presence of high SNR values that are found both in Urban and Rural Environments. We consider OFDMA scheme with an AWGN channel and analyze their performance in terms of the BER in the system.
In this correspondence, we propose a blind carrier phase synchronization algorithm for high-order M-ary quadrature amplitude modulation-orthogonal frequency division multiplexing (M-QAM-OFDM) systems, which can effectively recover residual frequency offset (RFO) in the presence of intercarrier interference (ICI). The proposed algorithm performs frequency and phase synchronization by using post-fast...
In this paper we consider the coexistence issue between OFDM-based WLANs of the 802.11a family and time-hopping ultra wideband (TH-UWB) systems. A general analytical expression is provided for the bit error rate (BER) of the OFDM transceiver operating in the presence of UWB interference and the interferences caused by the multipath propagation phenomenon on the 802.11a OFDM signal, comprising intersymbol...
