Patent ID: 7068715

Claim:
A radio communication system comprising: a transmitter for transmitting a plurality of continuous noise transmitted waveforms separated by a time interval D, wherein the transmitted waveforms are encoded by a relative polarity of two instances of the plurality of continuous noise transmitted data; and a receiver for receiving the plurality of continuous noise transmitted waveforms transmitted by the transmitter, the receiver comprising: a bank of correlators, each correlator in the bank of correlators being tuned to a different delay, each correlator of the bank of correlators comprising: a multiplier for multiplying delayed and undelayed versions of the received signal; and an integrator connected to the multiplier for integrating an signal output by the multiplier; a code word correlator connected to the integrator for correlating a code word corresponding to N C chips, each of the N C chips comprising a continuous noise transmitted waveform separated by a fixed time interval.
