Correlator and synchronous tracking apparatus using time sharing of a received signal in a spread spectrum receiver |
摘要 |
In the synchronous tracking apparatus of a spread spectrum receiver, data obtained by multiplying a receive signal by a pseudo-noise code for receiving is time-shared by differing time-sharing circuits, first and second correlation properties are created which are asymmetrical on both sides with respect to a correlation value axis in which the phase difference between a pseudo-noise code for transmitting contained in the receive signal and a pseudo-noise code for receiving is 0, a delay discriminating property is created by combining these correlation properties, a pseudo-noise code for receiving is controlled based on this delay discriminating property and the pseudo-noise code for transmitting tracks the pseudo-noise code for receiving.
