Abstract (en)

[origin: WO0007323A1] A method of forward error correction for communication systems, comprising the steps of producing a symbol stream by forward error coding of a data stream, modulating the symbol stream to produce a modulated signal, transmitting the modulated signal over a communication link, receiving the modulated signal, where the received modulated signal includes errors, demodulating the received signal which includes errors, decoding the demodulated signal by a plurality of convolutional decoders, and, regenerating the data stream and eliminating the errors. A method of peak power level reduction for communication systems utilizing a plurality of coders comprising the steps of producing a peak reduced signal by encoding the data stream by the plurality of coders, modulating the peak reduced signal, and, transmitting the modulated peak reduced signal. An apparatus is described for implementing the method.
