New designs of frequency selective FIR digital filters
Fourier series expansion is used to explore the relationship between the coefficients of halfband lowpass and general bandpass FIR digital filters. This relationship is used to de...

Bit-Width Selection for Data-Path Implementations
Specifications of data computations may not necessarily describe the ranges of the intermediate results that can be generated. However, such information is critical to determine t...

A Reduced-PAR Opportunistic STBC Scheme for Frequency-Selective Channels in the Presence of Frequency Offset
Opportunistic space-time block codes (STBC) have been investigated for flat-fading channels in the literature. In this paper, we present a novel scheme for integrating them with or...

Minimizing memory access energy in embedded systems by selective instruction compression
We propose a technique for reducing the energy spent in the memory-processor interface of an embedded system during the execution of firmware code. The method is based on the idea ...

Potentials of Opportunistic Routing in Energy-Constrained Wireless Sensor Networks
The low quality of wireless links leads to perpetual packet losses. While an acknowledgment mechanism is generally used to cope with these losses, multiple retransmissions neverthe...
