In this paper, we investigate the effects of phase noise in the presence of imperfect channel estimation (ICE) on the performance of Orthogonal Frequency Division Multiplexing (OFDM) wireless systems with receive diversity employing maximal ratio combining (MRC) and transmit diversity for Space-Time Block Codes (STBC) with multiple transmit antennas and one receive antenna in a Rayleigh fading environment...
In this paper, we investigate the effects of RF impairments and imperfect channel estimation (ICE) on the performance of Orthogonal Frequency Division Multiplexing (OFDM) wireless systems with transmit diversity for Space-Time Block Codes (STBC) employing Nt : Nt isin [2,3,4] transmit antennas and one receive antenna in a Rayleigh fading environment. The bit error rate (BER) expressions of the OSTBC-OFDM...
In this paper, we investigate the effects of RF impairments and imperfect channel estimation (ICE) on the performance of quadrature amplitude modulation (QAM) for orthogonal frequency division multiplexing (OFDM) systems employing transmit diversity with two transmit antennas and one receive antenna in a Rayleigh fading environment. We derive the bit error rate (BER) expressions of space-time block...

In this paper, we investigate the effects of RF impairments and imperfect channel state information (CSI) on the performance of M-QAM orthogonal frequency division multiplexing (OFDM) employing maximum ratio combining (MRC) receiver architecture in Rayleigh fading channels. We derive the BER expressions for M-QAM OFDM with the effects of the RF impairments and employing R-branch MRC receiver structure...
This paper provides the analysis of the joint effects of oscillator phase noise and channel estimation errors on the performance of OFDM in Rayleigh fading channels. The contribution of the above impairments to the signal distortion is mathematically described, and a proof of the distribution of the intercarrier interference (ICI) is also provided. Analytic and simulation results for the bit error...
