چکیده
The analytical bit error rate of hierarchical quadra5 ture amplitude modulation formats, which include uniform and 6 nonuniform constellations, over flat Rayleigh fading environments 7 is studied in this paper. The analysis takes into account the effect 8 of imperfect channel estimation and considers diversity reception 9 with both independent identically and nonidentically distributed 10 channels, employing maximal ratio combining. 11

Performance bound for generalised multilevelquadrature amplitude modulations constellations in multipath Rayleigh fading channels with imperfect channel estimation
The authors derive a lower bound on the performance of generalised multilevel quadrature amplitude modulations (MQAM) in time-discrete multipath Rayleigh fading environments with imperfect channel estimation. The bound can be regarded as an extension of the well-known matched filter bound (MFB), taking into account the impact of imperfect channel knowledge. The analytical expressions derived al...
متن کاملExact BER Analysis for Alamouti’s Code on Arbitrary Fading Channels with Imperfect Channel Estimation
In this contribution, we investigate the effect of imperfect channel estimation on the bit error rate (BER) performance of multiple-input multiple-output (MIMO) systems employing Alamouti’s code. The propagation channels from both transmit antennas to each of the Nr receive antennas are assumed to be affected by (possibly correlated) flat block fading with an arbitrary fading distribution. The ...
متن کاملEffect of channel estimation error on M-QAM BER performance in Rayleigh fading
We determine the bit-error rate (BER) of multilevel quadrature amplitude modulation (M-QAM) in flat Rayleigh fading with imperfect channel estimates. Despite its high spectral efficiency, M-QAM is not commonly used over fading channels because of the channel amplitude and phase variation. Since the decision regions of the demodulator depend on the channel fading, estimation error of the channel...

متن کاملBer of Mrc for M-qam with Imperfect Channel Estimation over Correlated Nakagami-m Fading
In this contribution, we provide an exact BER analysis for M-QAM transmission over arbitrarily correlated Nakagamim fading channels with maximal-ratio combining (MRC) and imperfect channel estimation at the receiver. Assuming an arbitrary joint fading distribution and a generic pilot-based channel estimation method, we derive an exact BER expression that involves an expectation over (at most) 4...
