Digital Binary Phase-shift Keyed Signal Detector
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
متن کاملmaxAlike: Sequence Reconstruction by Maximum Likelihood Estimation
The task of reconstructing a piece of sequence in a particular species is gaining more and more importance in the light of the rapid development of high-throughput sequencing technologies and their limitations. Applications include not only compensation for missing data in unsequenced genomic regions but also the preparation of customized queries for homology-based searches. Here, we introduce ...
متن کاملMulti-channel Maximum Likelihood Sequence Estimation
In mobile radio communications, antenna arrays can be used to improve the quality and/or the capacity of the communication system. The combination of an antenna array and maximum likelihood sequence detection (MLSE) is studied here. Diierent realizations of the multi-channel MLSE are presented. Although equivalent in performance, it is pointed out that one of them, the multi-dimensional matched...
متن کاملOn the correct modeling of semiconductor optical amplifier RIN and phase noise for optical phase shift keyed communication systems.
Phase modulation schemes are attracting much interest for use in ultra-fast optical communication systems because they are much less affected by fiber nonlinearities than conventional modulation formats. Semiconductor optical amplifiers (SOAs) can be used to amplify and process phase modulated signals. However, existing SOA nonlinear phase noise (NLPN) models are simplistic and, sometimes, inac...
متن کاملNew Pseudo Random Binary Sequence Phase Shift Keyed Signals for Electrical Measurement
The two well known digital signals used in system identification are the squarewave and Pseudo Random Binary Sequence (PRBS) signals. In data measurement, symbols with the aid of the identification coding theorems are used to capture information using an identification channel. Previously signal engineering design techniques involving descriptive languages, symbolic codes, shift keyed symbols w...
