چکیده

We present a generic approximation of the packet error rate (PER) function of uncoded schemes in the AWGN channel using extreme value theory (EVT). The PER function can assume both the exponential and the Gaussian Q-function bit error rate (BER) forms. The EVT approach leads us to a best closed-form approximation, in terms of accuracy and computational efficiency, of the average PER in block-fading channels. The numerical analysis shows that the approximation holds tight for any value of SNR and packet length whereas the earlier studies approximate the average PER only at asymptotic SNRs and packet lengths.

Approximations of the packet error rate under quasi-static fading in direct and relayed links

The packet error rate (PER) is a metric of choice to compute the practical performance of communication systems experiencing block fading, e.g., fading processes whose coherence time is relatively slow when compared to the symbol transmission rate. For these types of channels, we derive a closed-form asymptotic expression which approximates the value of the PER for high signal-to-noise ratio (S...

Performance analysis of time-hopping ultra-wideband systems in multipath fading channels (uncoded and coded schemes)

In this paper, we evaluate the performance of both uncoded and coded multiple access TH-UWB systems introduced in [1-3], in multipath Rayleigh fading channels. The receiver is a selective diversity combining receiver, known as SRake. Based on Gaussian distribution assumption for the multiple access interference at the output of SRake receiver and by using virtual branch technique as introduced ...

Energy Level Performance of Packet Delivery Schemes in Wireless Sensor Networks over Fading Channels

Energy level performance of three packet delivery schemes in a Wireless Sensor Networks (WSNs) over fading channels is evaluated. Effects of two short term fading such as Rayleigh and Rician on packet delivery schemes are evaluated. Three different information delivery mechanisms are considered using regenerative relays with or without error correction capability. In all the three schemes, mess...

Power loading for CP-OFDM over frequency-selective fading channels

In this paper we compare cyclic prefix (CP) based single and multicarrier block transmission schemes in frequencyselective fading channels. Analytical comparison shows that at moderate-to-high signal-to-noise ratio (SNR), the uncoded error rate performance of multicarrier transmission is inferior to that of single carrier. We propose new minimum bit error rate (MBER) power loading algorithms fo...
