Patent Images
1. A method of improving noise immunity in a signal representing communication or radar data, the method comprising:
- receiving at a communications system, comprising a receive device, a multi-bit symbol comprised of pulses and absences of pulses, wherein the multi-bit symbol represents communication or radar data;
incrementing a correlation count if a pulse is present when a pulse is expected; and
decrementing the correlation count if a pulse is present when a pulse is not expected.

Abstract
A method of improving noise immunity in a signal is provided. The method comprises receiving a multi-bit symbol comprised of pulses and absences of pulses, incrementing a correlation count if a pulse is present when a pulse is expected, and decrementing the correlation count if a pulse is present when a pulse is not expected.

7. A computer program product, comprising:
a non-transitory computer-usable medium having computer-readable instructions embodied therein for configuring a computer processor, the computer program product comprising; first instructions configured to cause a computer processor to compare a received multi-bit symbol comprised of pulses and absences of pulses to an expected pattern of pulses and absences of pulses; second instructions configured to cause a computer processor to increment a correlation count when the received multi-bit symbol matches the expected pattern; third instructions configured to cause a computer processor to decrement the correlation count when the received multi-bit symbol does not match the expected pattern; and fourth instructions configured to cause a computer processor to compare the correlation count to a threshold value. - View Dependent Claims (8, 9, 10, 11, 12)

13. A communications system, comprising:
-
a transmit device adapted to transmit a multi-bit symbol, the transmit device being adapted to modulate the multi-bit symbols using a pulse-based modulation scheme; and a receiving device adapted to accept the received multi-bit symbol when a correlation count exceeds a threshold value and reject the received multi-bit symbol when the correlation count does not exceed the threshold value, wherein the receiving device increments the correlation count if a pulse is present when expected and decrements the correlation count if a pulse is present when a pulse is not expected. - View Dependent Claims (14, 15, 16, 17, 18)

19. A communications system, comprising:
-
means for transmitting a multi-bit symbol comprised of pulses and absences of pulses; and means for receiving the multi-bit symbol, wherein the means for receiving the multi-bit symbol increments a correlation count when a pulse is present when a pulse is expected and decrements the correlation count when a pulse is present when a pulse is not expected. - View Dependent Claims (20, 21, 22)
