A New Optimal Biphase Pulse Compression Codes based on Cosine Mapping
Abstract: In proposed method a new optimization algorithm based on cosine mapping is introduced for radar pulse compression. The algorithm generate optimal chaotic biphase sequence having good autocorrelation and cross correlation properties. The sequence produces inherently small side lobes in autocorrelation function (ACF) of matched filter. Reduced values of side lobe level signify the optimal values of merit factor (MF) and peak side lobe level (PSL) and hence enhancement in radar …

Performance Analysis of Efficient Channel Coding Schemes for Deep Space and Interplanetary Missions
Abstract: This paper discusses about the space communication challenges – especially deep space communications with a detailed analysis on channel coding techniques and modulation schemes. It explains about the free space loss (FSL) that occurs due to the presence of long distances (in terms of Astronomical Units) in AWGN channel with relation to the power transmitted and power received. Also, it discusses different kinds of digital modulation techniques employed in tandem …
