The Newglee NGA-201A Drm modulator is a cutting-edge core device for DRM baseband processing, designed to meet the ETSI ES 201 980 standards. Built on an embedded platform, this modulator is equipped with advanced channel coding and OFDM modulation capabilities. It receives MDI/DCP streams from DRM encoders to generate signals compliant with DRM specifications.
Channel Coding and OFDM Modulation: Generates ETSI ES 201 980-compliant I/Q signals from MDI/DCP streams.
Peak-to-Average Power Ratio Reduction: Lowers OFDM PAPR, boosting transmitter efficiency.
Digital Pre-Distortion: Optimizes signal quality through compensation.
Multiple Output Modes: Supports I/Q, envelope/phase-modulated, and direct RF outputs for versatile transmitter compatibility.
