iv ACKNOWLEDGEMENTS This thesis would have been impossible without support of many people. I would like to express my sincere gratitude to them, though their invaluable support deserves much more than this short note of appreciation. It is difficult to overstate my gratitude to my advisor Prof. Tamal Mukherjee and Jeyanandh Paramesh. Their enthusiastic and inspirational leadership in research h...

We describe the architecture and algorithm development for a field programmable gate array (FPGA) wideband telemetry receiver prototype capable of processing data rates in excess of 100 megabits per second (Mbps). The high-speed parallel implementations of the matched filter, carrier phase tracking loop, and symbol timing recovery loop are discussed, along with simulation and hardware performan...

Closed-form expressions for the average signal-tonoise ratio (SNR) and amount of fading are derived for a rake receiver using maximal-ratio combining on the IEEE 802.15.3a ultra-wideband (UWB) channel model. It is also shown that all moments of the SNR and all joint moments of the channel coefficients can be expressed in closed form.

Mobile wireless terminals tend to become multi-mode wireless communication devices. Furthermore, these devices become adaptive. Heterogeneous reconfigurable hardware provides the flexibility, performance and efficiency to enable the implementation of these devices. The implementation of an WCDMA and an OFDM receiver in the same coarse-grained reconfigurable MONTIUM processor is discussed. Keywo...

In this paper a 75 pJ/b all-digital quadrature coherent impulse radio ultra-wideband transceiver in 0.18μm CMOS is presented. It consumes 42mW operating at a 560Mbps datarate. The receiver and transmitter share most of the components reducing the area. This design is optimal for low-power low-cost short-range high-speed communications.

This paper investigates the performance of the high speed 2-parallel MB-OFDM ultra-wideband (UWB) receiver. Achieving high speed and low complexity become a challenge of UWB system design. In our solution, a highspeed low-complexity 2-parallel MB-OFDM UWB system with fixed point data type will be described and simulated.

This paper presents a comparison of different detection methods which could be used to sense a frequency band in order to select a particular channel and a particular communication standard in a wideband melted signal. Here we focus on a generic WLAN receiver based on SDR principles, capable of sampling several overlapping channels to demodulate simultaneously concurrent users possibly using di...

Joint synchronization and calibration of multi-channel transform-domain charge sampling receivers (May 2009) Pradeep Kotte Prakasam Chair of Advisory Committee: Sebastian Hoyos Transform-domain (TD) sampling is seen as a potential candidate for wideband and ultra-wideband high-performance receivers and is investigated in detail in this research. TD receivers expand the signal over a set of basi...
