Lattice implementation of adaptive channel shortening in multicarrier transmission over IIR channels
Time-domain equalization is crucial in reducing channel dispersion and canceling interference in multicarrier systems. The equalizer is a finite impulse response (FIR) filter with the purpose that the delay spread of the combined channel-plus-equalizer IR is not longer than the cyclic prefix length. In this paper, a specific framework of long FIR channel-shortening problem is studied. In fact, ...
متن کاملAdaptive sub-channel equalization in multicarrier transmission
In multicarrier data transmission using filter banks, adaptive equalizers can be introduced in the receiver in every sub-channel, to achieve high bit rates. Following conventional data transmission techniques, two approaches can be envisaged, namely the double sampling equalizer (DSE) and the critical sampling equalizer (CSE). Both schemes are discussed and assessed in the present paper, in the...
متن کاملBuffer and channel adaptive modulation for transmission over fading channels
We consider the problem of adaptive modulation for increasing the throughput of transmission over fading channels. In the model, packets arrive at a finite-length buffer according to a Poisson distribution and are mapped into M-ary quadrature amplitude modulated (MQAM) symbols for transmission over a correlated Rayleigh fading channel. We assume that buffer and channel state information are alw...
متن کاملTime Domain Channel Shortening for Multicarrier Systems
Multi-Carrier (MC) modulation has various advantages that make it useful for a wide variety of digital communication systems. Actually, it has been chosen as the physical layer standard for a diversity of basic systems such as digital transmission over telephone lines, applications in broadcasting and in wireless networks. The most important advantage of the MC system is its robustness against ...
متن کاملThreshold - Free Erasure Decoded Multicarrier Local Transmission over Multipath Channels
SUMMARY In order to exploit fully the frequency diversity benefits of multicarrier modulation (MCM), and the very nature of the frequency selective radio channel, we investigate an erasure decoded π/4 QDPSK MCM (ED-MCM) by employing simple Hamming (block) code. We propose the threshold-free criteria, i.e. relative minimum receive power test (RMRPT) and relative maximum decision error test (RMDE...
