Compressive detection of direct sequence spread spectrum signals
Electronics Letters, 2018 In spread spectrum (SS) communications, the input signal is spread over a wider bandwidth to avoid interference or interception. One of the most common SS techniques is direct sequence SS (DSSS).

2017 IEEE 8th Control and System Graduate Research Colloquium (ICSGRC), 2017
This paper presented an enhanced of SINR based on serving and neighboring path loss to mitigate co-channel interference by using DSSS technique in LTE-Wi-Fi network. The proposed technique is the continuity from the earlier work which enhanced the DSSS with new coefficient: chip rate coefficient and radius fraction coefficient.

MILCOM 91 - Conference record, 2002
Prediction error filter (PEF) design for narrowband interference (NBI) excision is examined for a hopped direct-sequence spread-spectrum system. The PEF is obtained by application of the Levinson Durbin algorithm (LDA). Several enhancements are utilized: unbiased autocorrelation estimation and normalization.

2007 IEEE International Symposium on Electromagnetic Compatibility, 2007
The goal of this paper is to analyze the effect of nonlinearities on the performance of direct-sequence spread spectrum systems in the context of electromagnetically diverse applications. Inter-modulation products due to nonlinear amplification are analyzed and the effect of nonlinearities is illustrated by means of a computer simulation result.
