Abstract:
Described herein is a method for signal regeneration, particularly, of the signal type transmitted by cellular base stations used in cellular telephone network systems. It is sometimes necessary to regenerate an accurate replica of a transmitted signal, by removing any errors that are present and/or compensate for any degradation that occur during transmission. The signal structure of signals transmitted within the cellular network systems is of a known form with predefined characteristics such as synchronization signals, error correction bursts or training sequences. The method includes determining frame timing of the received signal, identifying the locations of sequences within the signal from the frame timing, identifying the structure of the sequences, estimating phase shift values at the locations of the sequences, demodulating the symbol stream using the estimated phase shift values and the structure of the sequences, correcting symbol errors by various techniques and remodulating the symbol stream using the phase shift values to regenerate the signal that is substantially identical to the one that would have been received directly from the transmitter over a high quality land-line.
