A programmable digital baseband receiver that processes a large number of signal waveforms and data rates. Programmable elements of the receiver implement coherent signal detection, automatic gain control and decision processing that permits processing of a large number of signal bandwidth efficient QAM and similar signal formats. The receiver comprises a threshold array having a plurality of programmable complex threshold detectors, and selectable decoder tree logic structures embodied in threshold interpreters. Each programmable complex threshold detector is a fully programmable I, Q threshold detector employing programmable I, Q sign threshold detectors that is adapted to the received complex baseband signal constellation.
