SIGNAL CODING FOR IMPROVED SPECTRAL QUALITY

摘要

A satellite communications system can use a spread-spectrum waveform and format, a synchronization scheme, and/or a power management algorithm. This approach can provide benefits such as allowing every terminal to communicate with every other terminal, link margin permitting. This gives the network a mesh topology although it can be configured in a star topology for highly asymmetric applications. A further understanding of the nature and the advantages of particular embodiments disclosed herein may be realized by reference of the remaining portions of the specification and the attached drawings.

1. A method for improving spectral characteristics in a transmitted signal, wherein the signal is generated at least in part by using an Orthogonal Variable Spreading Factor (OVSF) matrix, the method comprising:
determining that at least a portion of the OVSF matrix does not have a desirable spectral property; and modifying the at least a portion of the OVSF matrix with a sequence having an improved spectral property.
