六、内容简介

Geographically Segmented Localcasting (GSL) aims to improve spectrum efficiency and deliver localized content by reusing frequencies within different geographic areas. However, this model is susceptible to co-channel interference among adjacent GSL towers, which requires specific mitigation technologies to ensure signal reception and service quality. Common mitigation techniques include frequency planning, power control, directional antennas, advanced modulation and coding schemes, and signal processing techniques that can effectively suppress or cancel interfering signals.
