摘要： A device and method for cancelling code interference in a receiver of a CDMA (Code Division Multiple Access) communication system simultaneously using orthogonal codes and quasi-orthogonal codes are provided. In a receiver according to an embodiment of the present invention, a channel estimator produces a channel estimation value of a pilot channel signal spread by an orthogonal code through despeading. A quasi-orthogonal channel receiver receives a channel signal spread by a quasi-orthogonal code, despreads the channel signal, demodulates the despread channel signal by use of the channel estimation value, and provides an output. An interference estimator estimates an interference value of the pilot channel signal with the channel signal spread by the quasi-orthogonal code by obtaining a correlation value between the orthogonal code corresponding to a pilot channel and the quasi-orthogonal code corresponding to a quasi-orthogonal channel. An interference canceller cancels the estimated interference from the output of the quasi-orthogonal channel receiver.

摘要： A method for performing a handoff when a mobile station receiving a transmission diversity signal travels from a first base station transmitting a signal in a transmission diversity mode of operation to a second base station transmitting a signal in the transmission diversity mode of operation. In the method, the mobile station communicates with the first base station in the transmission diversity mode of operation. Prior to performing handoff, the mobile station communicates with the first base station in a non-transmission diversity mode of operation. During the handoff, the mobile station communicates with the first and second base stations in the non-transmission diversity mode of operation. Upon completing the handoff, the mobile station communicates with the second base station in the non-transmission diversity mode of operation. After a predetermined time, the mobile station communicates with the second base station in the transmission diversity mode of operation. Other methods for performing the handoff are also provided where, for example, the mobile station and the base stations operate in the transmission diversity and the non-transmission diversity modes of operation.

摘要： A PN sequence identifying device in a receiver in an asynchronous CDMA communication system. The receiver receives first OGCs on a primary sync channel and second OGCs on a secondary sync channel synchronized with the primary sync channel symbol by symbol. In the PN sequence identifying device, a first OGC detector detects the first OGCs and obtains a first symbol energy. A first synchronizer receives the first symbol energy, synchronizes chips, symbols, and slots, and outputs a first sync signal. A second OGC detector, upon reception of the first sync signal, detects the second OGCs each time the first sync signal is received, and obtains second symbol energies in base station identifying group units. A hopping pattern generator compares the first symbol energy with the second symbol energies, determines whether null signs are in the second OGCs, determines the order of the null signs if the null signs are present, and generates a hopping pattern of the second OGCs. A second synchronizer synchronizes frames based on the hopping pattern and outputs a second sync signal. A PN sequence generator receives the first and second signals and the hopping pattern and generates a PN sequence.

摘要： In a code division multiple access (CDMA) communications system, a PN sequence generating device is provided to generate a PN sequence by interleaving of cyclically shifting the symbols of an orthogonal or biorthogonal code in accordance with a pre-defined hopping pattern. A receiver receives simultaneous signals from a plurality of transmitters, where each transmitted signal is spread by a PN sequence generated from the same pre-defined hopping pattern. The receiver is able to differentiate the received signals from each transmitter by varying the amount of interleaving or cyclic shift in each transmitted signal. In the PN sequence generating device, an orthogonal symbol generating portion cyclically shifts mutually orthogonal and periodic orthogonal code sequences, and an orthogonal symbol selector selectively outputs the cyclically shifted orthogonal symbols according to a predetermined pattern.
