Analysis of RF Front-End Non-linearity on Symbol Error Rate in the Presence of M-PSK Blocking Signals
… in the non-linear region, this will affect the system performance due to intermodulation products, and cross-modulation, to name a few. Intermodulation products are the result of adjacent channel signals that combine and create intermodulation distortion of the received signal. We call these …

Transmit Precoder Design for Dual-Function Radar-Communication Systems
… grow, the ability to conduct multiple RF system functions from a common aperture is being realized. Conducting both radar and communications functions from the same system is potentially useful for vehicular, health monitoring, and surveillance applications. This paper considers …

Oscillator Phase Noise Reduction Using Nonlinear Design Techniques
… is one of the major limiting factors affecting communication system performance. Phase noise directly effects short-term frequency stability, Bit-Error-Rate (BER), and phase-locked loop adjacent-channel interference. RF oscillator circuits contain at least one active device, usually a …

EM-Based iterative channel estimation and sequence detection for space-time coded modulation
… detection of signals transmitted over a wireless communication channel requires knowledge of the channel estimate. In this work, the application of expectationmaximization (EM) algorithm to estimation of unknown channel and detection of space-time coded modulation (STCM) signals is investigated. …

Unreliable and resource-constrained decoding
Traditional information theory and communication theory assume that decoders are noiseless and operate without transient or permanent faults. Decoders are also traditionally assumed to be unconstrained in physical resources like material, memory, and energy. This thesis studies how constraining …

Implementation and Analysis of Wireless Local Area Networks for High-Mobility Telematics
Wireless networks provide communications to fixed, portable and mobile users and offer substantial flexibility to both end-users and service providers. Current cellular/PCS networks do not offer cost effective high data rate services for applications, such as, telematics, traffic surveillance and …
