Correlations in coalescence times between two loci are derived under selectively neutral population models in which the offspring of an individual can number on the order of the population size. The correlations depend on the rates of recombination and random drift and are shown to be functions of the parameters controlling the size and frequency of these large reproduction events. Since a pred...

Positive selection on a new mutant allele can increase the frequencies of closely linked alleles (through hitchhiking), as well as create linkage disequilibrium between them. Because this disequilibrium is induced by the selected allele, one may be able to identify loci under selection by measuring the influence of a candidate locus on pairwise disequilibrium values at nearby loci. The constrai...

A statistical departure from Mendel's law of segregation is known as transmission ratio distortion. Although well documented in many other organisms, the extent of transmission ratio distortion and its influence in the human genome remains incomplete. Using Genetic Analysis Workshop 19 whole genome sequence data from 20 large Mexican American pedigrees, our goal was to identify potentially dist...

Time-domain equalizers (TEQ) are used in the discrete multitone (DMT) transceivers in order to reduce the duration of the overall response of the transmission system, so that a shorter-length cyclic prefix could be used. The optimum TEQ is the one that results in maximum bit allocation to each block of DMT. However, the optimum design of TEQs turns out to be a very difficult task. In this paper...

High peak-to-average power ratio is a major problem that is inherent in all multicarrier communication systems. Clipping the high-peak power samples introduces (extra) clipping noise, which degrades the system performance in terms of bit-error rate (BER). Measuring BER usually requires a very long simulation time, as clipping occurs very rarely. In this letter, we propose a method called clippi...

Another Application for Trellis Shaping: PAR Reduction for DMT (OFDM) Werner Henkel, Member, IEEE, and Björn Wagner Abstract—A bound for the possible reduction of the peak-to-average ratio (PAR) dependent on the rate as well as possible practical procedures are presented. The idea of trellis shaping, originally used to minimize average transmit power in single-carrier systems, is applied to the...

This paper proposes a new blind adaptive channel shortening approach for multi-carrier systems. The performance of the discrete Fourier transform-DMT (DFT-DMT) system is investigated with the proposed DST-DMT system over the standard carrier serving area (CSA) loop1. Enhanced bit rates demonstrated and less complexity also involved by the simulation of the DST-DMT system.
