Transmitter Combining DRM for FM: Building an Extended DRM Multiplex

Transmitter combining is ideal for closely packed DRM signals and can be used effectively with analog channel combiners at shared transmission sites for signals spaced out in frequency.

The ability to freely mix and combine analog and multiple digital DRM signals, in adjacent channels, with individually varying power levels, supporting single frequency networks, allows broadcasters, network regulators and frequency planners a new dimension of possibilities for planning and operating digital radio networks using established planning parameters for both DRM and FM services.

In an expertly article of the professional journal of IEEE (Institute of Electrical and Electronics Engineers) Philipp Schmid, chief technology officer at Nautel, and Stefan Galler, chief executive officer at RFmondial, report about the exciting development of this concept.
