In a wireless transmission system that transmits the same information in parallel using two, or more different types of modulation schemes such as a satellite-based , digital audio transmission system transmitting two TDM signals and a single OFDM signal a receiver , processes the, differently modulated signals to generate separate demodulated signals that are then combined to, form a single combined signal for further processing (e.g. decoding). In one embodiment, the, receiver applies a maximal ratio combining (MRC) technique to generate a single optimal ratio, combined signal from the differently modulated signals. By combining the differently modulated, signals using an MRC …

Why it's free to use
- Filed October 11, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 11, 2020.
