| 20120108193 | Method and Apparatus for Forming a Beam - A device for forming a beam of an antenna array, the device including: an antenna array having a plurality of spatially distributed elements; a processor for selectively switching said elements between first and second states wherein, in said first state, said elements are configured to receive an incoming signal; and a receiver operatively associated with said antenna array and said processor for generating a reference signal, mixing said incoming signal with a modified reference signal to generate a mixed signal and summing the mixed signal over a predetermined period to generate an accumulated signal, wherein said reference signal is modified prior to being mixed with said received signal such that said accumulated signal is indicative of the direction and magnitude of the beam of the antenna array. | 05-03-2012 |
| 20100188291 | Staccato pulse edge correlation - The present invention discloses a system and method for mitigating multipath in DSSS CDMA radio navigation signals by a) transmitting a rapid pulsing pattern from a transmitting device to a position receiver that samples the transmitted signal, b) separating the received samples and storing sample-based correlation accumulation values into independent bins that are synchronous with the received pulsing pattern, c) applying a logical decision process to determine the accumulation bin associated with the leading edges of the received pulses, and d) generating a range estimate from the correlation accumulation bin associated with the leading edges of the received pulses. | 07-29-2010 |
