Title: Range-finding and position-measuring method using spread spectrum signal, and apparatus for executing the method
Inventor: TSUNEHARA KATSUHIKO
IPC: G01S19/25
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To accurately measure the timing of reception of an incoming wave, having shortest propagation delay time for a spread spectrum signal, even in a multipath environment. SOLUTION: A first threshold timing detecting part 103, using both a delay profile originated by a delay profile-generating part 102 and a first threshold 330 inputted thereto from a first threshold-calculating part 105, selects from timings for which the correlation value of the delay profile is at its maximum timing, which exceeds the first threshold and which provides the fastest timing of reception. A reference timing calculating part 106, using the reception timing and a second threshold 331 inputted thereto from a second threshold calculating part 107, calculates the reference timing needed to calculate the reception timing of an incoming wave having the shortest delay time.  A reception timing calculating part 108 causes the timing which deviates from the reference timing by a preset time, to be outputted as the timing of reception 113 of the incoming wave having the shortest propagation delay time.

Title: Wide-band digital receiver
Inventor: YOKOI ATSUYA
IPC: H04B1/26
Filed: 2000-07-24
Abstract: PROBLEM TO BE SOLVED: To solve the problem that conventionally an IF frequency cannot be increased very high, since error noise is produced by the aperture jitter characteristics of a sampling signal supplied to an A/D converter in A/D conversion, and the valid number of bits (ENOB) is deteriorated, when a high-frequency reception signal is converted to an IF signal and is further converted into a digital signal by the A/D converter.

The A/D and D/A converters 8 and 9 are operated by the sampling signal generated by the same signal generator 10, thus inhibiting the generation of error noise in conversion by aperture jitter. The output of the D/A converter 9 is subjected to bandwidth lamination by a required frequency by a filter 11 for converting into the digital signal by a second A/D converter 12.
