A PC driven HF broadcast receiver concept for enhancing the use of the HF broadcast bands

摘要

Shortwave communications bas been experiencing a resurgence of interest in the past few years, not only for traditional services such as broadcasting, but also for other new mobile and fixed services. The impetus behind such interest is attributed to advances; in semiconductor technology, which may be exploited to improve the performance and reliability of different services. Using this philosophy, the paper describes a new concept, using the ubiquitous personal computer to enhance the operation of an HF broadcast receiver, it also gives an opportunity to support other technical and operational features for an improved future HF broadcasting service.
