The effect of spatial diversity on the throughput and reliability of wireless networks is
examined. Spatial diversity is realized through multiple independently fading …

Within the wide range of issues related to 4G wireless networks, due to the scope of the
ISSTA conference, in this presentation we highlight some segments of wireless networks …

Traditionally, a transport protocol corrects errors in a computer communication network
using a simple ARQ protocol. With the arrival of broadband networks, forward error …

An adaptive coding scheme for digital communication over time-varying channels is
presented. The scheme is based on a finite-state Markov channel model. Emphasis is on the …

An analysis is presented of the selective-repeat type II hybrid ARQ (automatic-repeat-
request) scheme, using convolutional coding and exploiting code combining. With code …

A method is presented to construct rate-compatible convolutional (RCC) codes from known
high-rate punctured convolutional codes, obtained from best-rate 1/2 codes. The …

Type-I hybrid-ARQ protocols can be used to construct powerful adaptive rate algorithms
through the use of packet combining techniques. In this paper several packet combining …

The quality of wireless links suffers from time-varying channel degradations such as
interference, flat-fading, and frequency-selective fading. Current radios are limited in their …

A generalized type II automatic-repeat-request (ARQ) scheme using punctured
convolutional coding on a two-state Markov model of a nonstationary channel is analyzed. A …

Type I hybrid ARQ systems use an error-control code of fixed rate for error-correction in each
transmitted packet. In such systems, the code rate must be carefully chosen to match the …
