Compatibility-Focused Upgrades
Our solutions prioritize seamless integration with various Envelope Elimination and Restoration (EER) transmitters, including PDM, PSM, and DX models. This versatility ensures a smooth upgrade process for any existing infrastructure, minimizing downtime and maximizing cost efficiency. By modernizing your transmission facilities instead of purchasing new equipment, you can achieve state-of-the-art performance while significantly reducing capital expenditure.
Enhanced Performance Metrics
Performance is critical in digital broadcasting. Upgraded systems deliver exceptional Modulation Error Ratio (MER) and Adjacent Channel Power Ratio (ACPR), ensuring crystal-clear audio and reliable data services. The upgrade also optimizes overall system efficiency, leveraging existing assets to reduce energy consumption and operational costs—enhancing your return on investment while future-proofing your broadcast infrastructure.
Energy Savings Advantages
In traditional AM broadcasting, over 90% of signal energy is concentrated in the carrier (based on a 30% average modulation rate). Achieving high signal-to-noise ratios (ITU requires ≥26dB) demands high field strength, large transmitter power, and substantial energy consumption.
DRM, a digital modulation technique that eliminates the carrier, requires only 1/10 to 1/20 of the transmission power compared to AM for the same coverage area. This reduction in power consumption translates directly into significant energy savings and lower operational costs.
DRM’s high spectral efficiency enables more information to be transmitted within the same bandwidth, further optimizing power usage per unit. Advanced modulators with PAPR suppression and transmitter optimization ensure compliance with strict DRM standards for MER and out-of-band emissions, maintaining signal integrity while minimizing spectral interference.
Sustainable Broadcasting Future
By upgrading to DRM, broadcasters can deliver superior audio and data services while supporting environmental sustainability through reduced energy consumption. This makes DRM an ideal solution for modernizing legacy infrastructure, ensuring long-term operational viability in an evolving broadcast landscape.
