Abstract
A broadcast digital transmission (BDT) receiver, computer-readable media, and associated method for receiving and processing of BDT signals from a plurality of transmitters. A BDT receiver includes an antenna to intercept broadcast radio signals and an analog front-end to down-convert it to a suitable frequency for digitization. A baseband signal processor acquires and tracks designated codes in BDT signals using a generalized correlator to produce time of arrival measurements thereof. A data processor, coupled to the baseband signal processor and with input from an auxiliary sensor and a digital database, first calibrates time offsets of said transmitters relative to the BDT receiver's time base and then operates on offset-adjusted time of arrival measurements to produce a position solution.
