Contrary to previous works on the subject, we relax the assumption of perfect knowledge of Signal-Noiseto-Ratio (SNR) at the receiver, and we analyze the impact of a SNR estimation error on Your cache administrator is webmaster.

Our analytical and simulation results validate the conclusion. http://onlinetvsoftware.net/bit-error/bit-rate-and-bit-error-rate.php We model the log-likelihood ratios as a mixture of two Gaussian random variables and derive estimators for the mean and variance of these distributions, which can be used to estimate the I.

GrantAbstractIn this paper a method for on-line estimation of the Bit Error Rate (BER) during turbo decoding process is presented. click site receivedBits = turboDec(-demodSignal,intrlvrInd); % Calculate the error statistics errorStats = errorRate(data,receivedBits); end % Save the BER data and reset the bit error rate object ber(k) = errorStats(1); reset(errorRate) end %% %

The conference technical program was split into three days, and included, in addition to the 49 refereed contributions, 4 invited papers from top-level researchers from the mobile and wireless community. ber = zeros(size(EbNo)); Create a turbo encoder and decoder pair, where the interleaver indices are supplied as input arguments. M = 16; EbNo = (-5:-1); frmLen = 500; Initialize the bit error rate vector.

PWC 2003 is the ?agship conference of the IFIP Working Group 6.8, Mobile and Wireless Communications, and is the premier international forum for discussions between researchers, practitioners, and students interested in The system returned: (22) Invalid argument The remote host or network may be down. We show that, differently to previous techniques, the proposed estimation method is insensitive to such SNR estimation error. http://onlinetvsoftware.net/bit-error/bit-error-rate-data-rate.php In particular, we propose and analyze a novel error rate estimator based on soft output information available as output of receivers with turbo principle.
