Optimal Logarithmic Representation in Terms of SNR Behavior
This paper investigates the Signal-to-Noise Ratio (SNR) performance of the Logarithmic Number System (LNS) representation against the SNR performance of the fixed-point representa...

High SNR Analysis for MIMO Broadcast Channels: Dirty Paper Coding vs. Linear Precoding
We study the MIMO broadcast channel and compare the achievable throughput for the optimal strategy of dirty paper coding to that achieved with sub-optimal and lower complexity lin...

Succinct Representations of Separable Graphs
Abstract. We consider the problem of highly space-efficient representation of separable graphs while supporting queries in constant time in the RAM with logarithmic word size. In p...

Using CLNS for FFTs in OFDM demodulation of UWB receivers
— The Complex Logarithmic Number System (CLNS) uses log/polar complex representation. We propose CLNS for the 128-point Fast Fourier Transform (FFT) in Orthogonal Frequency Divis...
