Title: Method and device for cancelling multiple access interference in code division multiple access(cdma) communication system
Inventor: KONG NING
IPC: H04B1/712
Filed: 2001-06-29
Abstract: PROBLEM TO BE SOLVED: To reliably cancel some interference generated by the transmission of other users in a noise component in the signal to noise radio of CDMA. SOLUTION: Improved reliability can be achieved by the combination of a conventional multistage parallel interference cancellation(MPIC) device, and the prospect of space and time diversity. The signal is received by a plurality of reception antennas 12 that are spatially separated, the space diversity is generated in a plurality of propagation paths, and the time diversity of a reception signal is generated. The signal is separated in a despreader 60 by the user. A processing module 62 maximizes the signal to noise ratio(SNR), thus selecting the appropriate subset of a multipath signal component that can be decomposed to each user. The selected signal generates the reliable set of the estimated value of a user signal by coherent combination for each user for connecting to the MPIC device in cascade for the repeated calculation of MAI to each user.

Title: Phase detector
Inventor: FUJIWARA TAKU
IPC: H04L27/38
Filed: 2001-07-02
Abstract: PROBLEM TO BE SOLVED: To obtain a 16QAM carrier phase detector using all signal points with a relatively simple circuit constitution. SOLUTION: When it is discriminated by a signal discrimination circuit 3 that a reception signal has the same phase as that of a signal point of the QPSK modulation system, a phase detector 101 in the 16QAM modulation system uses an in-phase signal I and a quadrature signal Q as they are. When the reception signal doesn't have the same phase as that of the signal point of the QPSK modulation system, the phase detector 101 discriminates an area where the reception signal exists, by a phase area discrimination circuit 4 and subjects the reception signal to phase rotation of a prescribed value by a complex multiplier 6 correspondingly to the area and uses an in-phase signal I' and a quadrature signal Q' which are converted so as to have the same phase as that of the signal point of the QPSK modulation system. Thus a 4-phase comparator 2 for QPSK can be used as it is, and the phase detector which uses all signal points of the 16QAM modulation system to obtain a reference carrier, is provided with a relatively simple circuit constitution.
