Joint Blind Symbol Rate Estimation and Data Symbol Detection for Linearly Modulated Signals

Joint Blind Symbol Rate Estimation and Data Symbol Detection for Linearly Modulated Signals

This paper focuses on non-data aided estimation of the symbol rate and detecting the data symbols in linearly modulated signals. A blind oversampling-based signal detector under the circumstance of unknown symbol period is proposed. First, the symbol rate is estimated using the Expectation Maximization (EM) algorithm. However, within the framework of EM algorithm, it is difficult to obtain a cl...

A ‘Frequency Blind’ Method for Symbol Rate Estimation

Estimation of the symbol rate has important applications in receiver synchronization for symbol time recovery. In this paper the problem is investigated using Smoothen Non-Linear Energy Operator (SNEO). Unlike wavelet based methods in [2], [3], [4] the proposed algorithm is completely blind because it does not require any priory information regarding the modulation type or carrier frequency. Mo...

Recursive blind symbol estimation of convolutionally coded cochannel signals

A recursive blind equalizer is presented that directly estimates the transmitted symbols of multiple cochannel signals in the presence of ISI. The algorithm exploits shift structure present in the data model and the finite alphabet property of the signals. The proposed method possesses a separation property that allows the symbol sequences for each user to be estimated independently of the othe...

Blind Joint Symbol Detection and DOA Estimation for OFDM System with Antenna Array

An analysis of the received signal of Orthogonal frequency division multiplexing (OFDM) system with array antennas shows that the received signal has trilinear model characteristics. Trilinear decomposition-based joint symbol detection and direction of arrival (DOA) estimation for OFDM system with antenna array is proposed in this paper. The simulation results reveal that the symbol detection p...
