Bit-Error-Rate Analysis of Raptor Codes over Rician Fading Channels
The bit-error-rate expressions of nonsystematic Raptor (NR) codes and systematic Raptor (SR) codes over Rician fading channels are first derived using a Gaussian approximation (GA) approach.

Time Domain Equalizer Design Using Bit Error Rate Minimization for UWB Systems
Ultra-wideband (UWB) communication systems occupy huge bandwidths with very low power spectral densities. This feature makes the UWB channels highly rich in resolvable multipaths.

Orthogonal Space Time Block Coding for Spatial Pulse Position Modulation
The system performance of Spatial Pulse Position Modulation (SPPM) is poor in turbulent channels. In order to solve this problem, the bit complement orthogonal space time Block Coding for Spatial Pulse Position Modulation (BCOSTBCSPPM) is proposed by ...

Invariance of the bit error rate in the ancilla-assisted homodyne detection
We investigated the minimum achievable bit error rate of discriminating binary coherent states by homodyne measurements with the help of arbitrary ancilla states coupled via beam splitters.

Spectrally Efficient DMT Operation With BER-Informed Dynamic Bit and Power Loading
This paper elucidates the relative benefits of bit loading and power loading for discrete multitone (DMT) modulation over wireline links. There is considerable variability in the use of bit and power loading in recent research on DMT for wireline ...
