Webcalculation shows that a simple 4-tap channel shortening filter consumes about two times the power of a 64-point IFFT1. Therefore, we will not consider a channel shortening filter for the system in our analysis. To make things even worse, IDFT block size itself cannot be made very large due to same complexity issues. WebNov 20, 2014 · Abstract: In this paper, we propose an efficient channel shortening algorithm, applied to OFDM systems, exploiting a particular decomposition of the …

WebJul 4, 2007 · Channel shortening filter, also known as time domain equalizer (TEQ), is generally used to reduce the effective length of a long multipath channel. This has the potential to reduce the cyclic prefix in a multitone based communication system such as asymmetric digital subscriber line (ADSL). The performance of a TEQ could however … WebWhen the memory of the channel is too large to be taken into account by a full complexity detector, excellent performance can be achieved by properly filtering the received signal followed by a reduced-state detector. This letter derives closed-form expressions for the front-end filter and the target response of the reduced-state detector. WebMay 4, 2024 · At the receiver, three partial-response detection schemes are investigated and compared: (1) constant modulus algorithm (CMA) + duobinary shaping + maximum likelihood sequence estimation (MLSE); (2) duobinary shaping + multimodulus algorithm (MMA) + MLSE; and (3) channel shortening filter. once was label
