Robust GMSK Demodulation Using Demodulator Diversity and BER Estimation
… diversity and real-time bit-error-rate (BER) estimation. GMSK is particularly important because of its use in promi- nent wireless standards around the world (GSM, DECT, CDPD, DCS1800, and PCS1900). The dissertation begins with a literature review of GMSK demodu- lation techniques …

Statistical Methods of Bit Error Rate Estimation in Optical Communication Systems
… thesis describes two methods of bit error rate (BER) estimation based on statistical techniques. The first method examines the correlation between the BER and electrical characteristics of an optical receiver circuit. Low correlation is found between the receiver performance and the electrical …

Probability Density Function Estimation Applied to Minimum Bit Error Rate Adaptive Filtering
… always guarantee minimization of bit error rate (BER). The main focus of this research involves estimation of the probability density function (PDF) of the received signal; this PDF estimate is used to adaptively determine a solution that minimizes BER. To this end, a new adaptive procedure called …

Design of mobile radio communication system at millimetre-waves and BER measurements for indoor environments
… modulated broadband system at 60 GHz and the estimation of Bit Error Rate (BER) performance in indoor mobile channels. A digital mobile radio system and high precision computer controlled positioning system have been designed and implemented to conduct measurements in a long narrow corridor …

Multiband orthogonal frequency division multiplexing for ultra-wideband wireless communication: analysis, extensions and implementation aspects
… novel analytical methods for bit error rate (BER) estimation for a general class of coded multicarrier systems (of which MB-OFDM is one example) operating over quasi-static fading channels. One method calculates system performance for each channel realization. The other method assumes Rayleigh …

Multi-dimensional direct-sequence spread spectrum multiple-access communication with adaptive channel coding
… device accelerates the system’sBit Error Rate (BER) to a so-called Pseudo Error Rate(PER) through a process known as threshold modification. It then uses a simple PER extrapolation algorithm to estimate the system’s true BER with moderate accuracy and without the need for known data. This study …
