Patent CA-2103305-C (CA)
Inventor: SCHOOLCRAFT RALPH W
IPC: H04B1/707
Filed: 1993-11-17
Granted: 2004-01-06
Abstract: A pseudo-noise (PN) correlation and demodulation method and apparatus, in which received signals are correlated with locally generated PN codes and correlation measurements are maintained for multiple time bins corresponding to signals received over possible multiple paths. Instead of selecting one or a small number of significant correlation measurements to control data demodulation, the method of the invention performs data demodulation over the multiple time bins, and then selects data values corresponding to significant correlation measurements and combines the selected data values, weighting them in accordance with their relative strengths a determined during correlation. Use of the invention provides improved performance in terms of signal quality and continuity in the presence of multipath conditions. Careful selection of design parameters allows the improved performance to be obtained in a compact and easily portable implementation including transmitter and receiver modules.

Title: Pseudo-random generator
Inventor: AIELLO WILLIAM ANTHONY
IPC: G06F7/58
Filed: 1995-01-18
Granted: 2000-04-18
Abstract: Methodology and concomitant circuitry to generate crytographically strong pseudo-random bit streams utilize secure block cypher encoders. Typically, each block cypher encoder (150) has a first seed (x?) and a random key (k) as an input. In the most basic realization of the methodology and circuitry, the ouput of each encoder is fed back (151) to connect to its input. The first seed serves as the initial input, and each subsequent input is the immediate output. Each bit in the crytographically strong pseudo-random bit stream is related (160) to an inner product between each input to the encoder and a second seed (h).
