Abstract: We investigate an improved upper bound on the bit error probability of turbo codes for the maximum likelihood (ML) decoding with imperfect channel state ...

Abstract: It has been demonstrated that the amplitude probability distribution (APD) of an interfering signal provides an approximation for the bit error probability ...

ABSTRACT: The BER performance for an optimal circular 16-QAM constellation is theoretically derived and applied in wavelet based OFDM system in additive white Gaussian noise channel. Signal point ...

Quantum data are susceptible to decoherence induced by the environment and to errors in the hardware processing it. A future fault-tolerant quantum computer will use ...

This file type includes high resolution graphics and schematics when applicable. The bit error ratio (BER) is defined as the probability that a bit is received in ...
