An ultrasound scanning method includes the steps of emitting N sets of ultrasound signals onto a target from N different angles and receiving the N sets of ultrasound signals reflected and/or scattered by the target; converting the N sets of ultrasound signals into N ultrasound input images; performing a binarization algorithm for the N ultrasound input images to obtain N binarized images; performing a comparison process on the N binarized images to determine whether a noise exists in at least one of the N binarized images; when the noise exists in an i-th binarized image of the N binarized images, removing the noise from an i-th ultrasound input image corresponding to the i-th binarized image; and compounding the N ultrasound input images into an ultrasound output image.

Ultrasound scanning method and system

The present invention provides a communication system, signal pre-processing apparatus and signal receiving apparatus thereof. The signal pre-processing apparatus is used for pre-processing signals before they are transmitted by a plurality of antennas. The apparatus includes a serial-to-parallel converter, L compensation processors and L beam formation processors. First of all, the serial-to-parallel converter converts a digital signal into N divided signals. Each of the compensation processors pre-compensates the N divided signals and outputs a compensated signal. Each of the beam formation processors intensifies the compensated signal and outputs an intensified signal. Each of the antennas combines L intensified signals into a particular signal, and meanwhile, upconverts the particular signal into a RF (radio-frequency) signal for transmission.

A method of Partial Parallel Interference Cancellation (PPIC) is provided for recursively eliminating the Multiple Access Interference from a received signal. Such method is to use a recursion way to eliminate all the Multiple Access Interference (MAI) one by one from the received signal. Moreover, the present invention is to take the output of the pre-stage as the input of the present stage with the recursion method so that we can use only one operating circuit to obtain the function the MAI eliminating.

Method of partial parallel interference cancellation

A method for data transmission rate adaptation for Wideband Code Division Multiple Access (WCDMA). The method includes A) providing a plurality of parameters, including: a maximum allowable transmission power, a minimum allowable transmission power, an increasing parameter and a decreasing parameter; B) receiving a signal; C) collecting a power excess parameter and a power deficient parameter in accordance to a transmission power control command controlling the signal's transmission power; D) determining whether the power deficient parameter is larger than the increasing parameter or not? If yes, increase the throughput, and then goes to step G, otherwise, goes to step E; E) determining whether the power excess parameter is larger than the decreasing parameter or not? If yes, reduce the throughput, and then goes to step G, otherwise, goes to step F; F) maintaining the throughput, goes to step G; G) end.

Method for data transmission rate adaptation

A Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) transceiver in which correlator banks consisting of an array of dual-code correlators (two tri-code correlators) are used to form correlator filters, such as chip matched filters or multi-code RAKE receivers, or FIR filters for CDMA/TDMA related applications.

Correlator/FIR filter unit for dual-mode transceiver

A correlator and matched filter for use with coded transmission, such as CDMA, form new codes from the sums and differences of the original codes, where only one of the new codes is non-zero for each element position and effect hardware savings using the new codes.

Methods and apparatus to despread dual codes for CDMA systems

Correlators categorize different combinations of code sequences and identify locations for which code elements for the code sequences are equivalent. Then, a dispreading operation is performed once for each equivalent combination. The equivalent combinations, for example, may be locations where the code elements are the same or locations where code elements are complements of one another.
