Abstract
An apparatus and method of processing transmitted signals through the use of correlator means and RAM means thereby accomplishing synchronization and data interpretation. Specifically, a plurality of correlators are coupled to RAM means which cooperate to store and subsequently read transmitted data. Clocking means used in conjunction with a programmed delay period provides segments of the received and stored data to a plurality of correlators and on to logic means for further processing.
Claims10
An apparatus for processing multi-frequency transmitted information received by multi-frequency receiver means comprising:
- temporary storage means for receiving input data and for providing the input data as output data at particular subsequent time delay intervals;
- means for controlling input data and output data with respect to the temporary storage means;
- a plurality of matched filter elements coupled to receiver means for receiving the output data;
- a plurality of latch means for receiving the output data from the temporary storage means and for performing a latching operation of catching data samples and transferring the data samples into said plurality of matched filter means;
- and
- summing means coupled to the plurality of matched filter means for combining the output of all matched filter means.
An apparatus for processing multi-frequency transmitted information received and digitized by multi-frequency receiver means comprising:
- a data bus for expanding the instantaneous length of the digitized data output of the receiver means;
- temporary storage means for receiving input data and for providing the input data as output data at particular subsequent time delay intervals;
- means for controlling input data and output data with respect to the temporary storage means;
- a plurality of matched filter elements coupled to receiver means for receiving the output data;
- a plurality of latch means for receiving the output data from the temporary storage means and for performing a latching operation of catching data samples and transferring the data samples into said plurality of matched filter means;
- and
- summing means coupled to the plurality of matched filter means for combining the output of all matched filter means.
