Diversity Selection Based o n Decoding Syndrome in Correlated Fading Channels
نویسنده
چکیده
In TDMA digital transmission for use in portable indoor mdiocommunications,oneof the impairmentsencountered is correlated slow fading. At low pomble speeds typical of slow user mobility in the indoor communications, the frequency and duntion of e m r bursts due to deep fades influence the choice of the Forward Error Correction scheme to be used. FUI is effective against Rayleigh fading only when used with interleaving [ 1][21. Concatenated coding and interleaving has also been shown to be useful in the mobile ndio channel [3]. The problem is that in the presence of deep fades FEC becomes useless without interleaving, and depending on the duration of the fade. interleaving will incur excessive delays.

Energy Detection of Unknown Signals over Composite multipath/shadowing Fading Channels
In this paper, the performance analysis of an energy detector is exploited over composite multipath/shadowing fading channels, which is modeled by Rayleigh-lognormal (RL) distribution. Based on an approximate channel model which was recently proposed by the author, the RL envelope probability density function (pdf) is approximated by a finite sum of weighted Rayleigh pdfs. Relying on this inter...
متن کاملA Blind Hammerstein Diversity Combining Technique for Flat Fading Channels
Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...
متن کاملTriple Selection Diversity over Exponentially Correlated Nakagami-m Fading Channels Desired Signal and Cochannel Interference
In this paper, system performances of selection combining over correlated Nakagami-m channels are analyzed. Selection diversity based on the signal to interference ratio (SIR) is a very efficient technique that reduces fading and cochannel interference influence. Fading between the diversity branches and between interferers is correlated and Nakagami-m distributed with exponential correlation m...
متن کاملRelay selection in cooperative networks with frequency selective fading
In this article, we consider the diversity-multiplexing tradeoff (DMT) of relay-assisted communication through correlated frequency selective fading channels. Recent results for relays in flat fading channels demonstrate a performance and implementation advantage in using relay selection as opposed to more complicated distributed space-time coding schemes. Motivated by these results, we explore...

LDPC lattices were the first family of lattices which have an efficient decoding algorithm in high dimensions over an AWGN channel. Considering Construction D’ of lattices with one binary LDPC code as underlying code gives the well known Construction A LDPC lattices or 1-level LDPC lattices. Block-fading channel (BF) is a useful model for various wireless communication channels in both indoor a...
