    摘要: 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.

    摘要: 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.

    摘要: 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.
