Abstract
The demodulation process of a wireless data transmission system using multi-level symbols makes use of templates corresponding to each of the possible symbol transitions, so that knowledge of previously decoded symbols can be use to decode the next one. The weighting and/or timing of individual samples of each symbol is varied in response to the performance of the symbol identification process.
Claims10
A demodulation process for demodulating a signal comprising a series of symbols having more than two modulation states, in which the impulse responses of the individual symbols extend over adjacent symbols, the identification of each symbol being made by measuring its shape from samples taken along its length, wherein the weighting and/or timing of individual samples is varied in response to the performance of the symbol identification process.
A receiver for receiving and demodulating a signal comprising a series of symbols having more than two modulation states, in which the impulse responses of the individual symbols extend over adjacent symbols, containing a symbol detector in which the identification of each symbol is made by measuring its shape from samples taken along its length, comprising means for weighting individual samples and/or changing their timing in response to the performance of the symbol identification process.
