IPC: H04B7/26
Filed: 2000-03-22
Abstract: Outer loop/weighted open loop power control controls transmission power levels in a spread spectrum time division duplex communication station. A first communication station (110) transmits a communication to a second communication station including target adjustment information generated at the first station on the basis of measured error rates of communications from the second station to the first station. The second station receives the communication and measures its received power level. Based on in part the received communication's power level and the communication's transmission power level, a path loss estimate is determined. A quality of the path loss estimate is also determined. The transmission power level for a communication from the second station to the first station is based on in part weighting the path loss estimate in response to the estimate's quality and based on the receive target adjusted by the target adjustment information transmitted from the first station.

Title: Tissue generating higher harmonic-enhanced imaging using encoding excitation
Inventor: CHIAO RICHARD YUNG
IPC: G01S7/52
Filed: 2001-01-30
Abstract: PROBLEM TO BE SOLVED: To provide tissue generating higher harmonic-enhanced imaging using encoding excitation for a medical ultrasonic imaging system. SOLUTION: Two-phase (1 and -1) encoding is performed on a transmitted waveform by using two code symbols in a code sequence for obtaining an N- nary higher harmonic signal. Each part (namely, each chip) of the transmitted waveform encoded by means of the second code symbol is shifted in phase by 180 deg./N against the chip encoded by means of the first code symbol. This processing is accomplished by shifting in time each part (each chip) of a transmitted sequence encoded by means of the second code symbol by the 1/2N period at the center frequency against each chip of the transmitted sequence. At the time of reception, emphasis is performed by decoding by separating a desired higher harmonic signal by means of a band-pass filter having a center frequency which is twice as high as that of a fundamental wave.
