Using Software DSP Solutions to Enhance Weak Signal Communications: An Updated User's Discussion of Linrad, SM5BSZ's Linux PC Radio

摘要

Linrad, a Software Defined Radio created by Leif Asbrink, SM5BSZ, has proven to be an extremely effective tool for weak signal communications. Its noise reduction and weak signal detection abilities are unparalleled, and it provides a comprehensive display of signal information that is vastly superior to all other alternatives. This article will provide a brief overview of DSP processing, and then present an introduction to this revolutionary 'receiver in software' which has replaced, for weak signal work, the conventional receivers at the author's station.
