Signal path system and method for a ranging signal receiver
Methods and receivers determine a range from radio frequency ranging signals at multiple frequencies. The number of dedicated RF sections and correlation processing power is reduced by multiplexing signals from a sub-set of frequencies onto a common path. The common path provides shared processing,...

Summary: | Methods and receivers determine a range from radio frequency ranging signals at multiple frequencies. The number of dedicated RF sections and correlation processing power is reduced by multiplexing signals from a sub-set of frequencies onto a common path. The common path provides shared processing, such as down-conversion shared by signals at two different frequencies. The correlation processing power for a three frequency receiver may be the same or similar as for a two frequency receiver since signals for two frequencies share processing as a function of time. Correlation is performed intermittently for signals at two of the frequencies. |
