Abstract
A proposed spread spectrum signal receiver includes a radio front-end unit and a processing unit. The radio front-end unit, in turn, has an antenna, a digitizing circuit and a primary buffer unit. The antenna is adapted to receive radio signals (S) from a plurality of signal sources, and the digitizing circuit is adapted to downconvert and filter the received signals (S), and generate sample values (S) thereof. The primary buffer unit is adapted to temporarily store the sample values (S) from the digitizing circuit and allow the processing unit to read out a first set of stored sample values (S) contemporaneously with the storing of a second set of sample values (S) in the primary buffer unit. The processing unit is adapted to receive the sample values (S) from the primary buffer unit, and based thereon, produce position/time related data (D).
