A Neural Network Receiver for EM-MWD Communication
… the depth at which EM-MWD systems can operate. Correlation receivers, which are optimal in the presence of additive white Gaussian noise, can be sub-optimal in the presence of various types of field noise at different drilling sites. </p> <p>This thesis investigates the application of artificial …

Sub-optimal Ultra-wide Band Receivers
… reduced complexity sub-optimal Ultra-Wide Band receivers. These receivers include auto correlation receiver, the square value detector and the absolute value detector are studied. We consider OOK and PPM modulation schemes. We examine these schemes and the receivers on Gaussian and UWB indoor …

Bit error rate simulation of a CDMA system for personal communications
… are compared. In the simulation, a RAKE receiver is implemented, the advantage of this RAKE receiver implementation is demonstrated by comparison to a single correlation receiver. Results for outage probability are also presented.

Multiuser detection for CDMA systems with convolutional coding
… of current systems which use a matched filter or correlation receiver. It has been shown by previous research that multiuser detection receivers employing interference cancellation techniques can significantly improve the capacity of COMA systems. Error correction coding is also an important …

Performance of Ds/ssma Communications in Impulsive Channels (Nongaussian, Hard Limiter)
Performance of digital linear and nonlinear correlation receivers is studied in a multi-user environment. There are assumed to be two types of sources interfering with data transmission: multiple-access interference, and additive channel noise, which is attributed to impulsive noise sources in the …

Channel modeling and interference rejection for CDMA automatic vehicle monitoring systems
It is desirable to develop a universal digital receiver which is capable of operating with many different wireless communication systems. Time Dependent Adaptive Filter (TDAF) Processing represents an effective approach for CDMA interference rejection. This technique is especially appropriate at …

Ultra-Wideband Channel Modeling using Singularity Expansion Method
… the output signal-to-noise ratio (SNR) of a correlation based matched-filter receiver, limiting the achievable data-rate and user capacity. Most wideband channel models do not account for all the identified dispersion mechanisms namely the frequency dispersion, the resonant dispersion and the …
