An architecture for a self-selective multi-rate transmitter that processes variable input rate data using a plurality of single input, multiple output interleavers. The transmitter, using a multitude of modulation formats, transmits the data at a constant symbol rate without a priori knowledge of the input rate. The transmitter employs a modulator that automatically selects between a multitude of signal constellations, depending on the rate of the source data to be transmitted. The modulator transmits data from various sources, each with an independent data rate. The modulator performs data formatting, forward error correction encoding, modulation onto an intermediate frequency, frequency conversion to a transmit radio frequency, and amplification with automatic gain control.
