摘要： A device for generating quasi-orthogonal codes which allow the minimum interference with orthogonal codes in a mobile communication system using the orthogonal codes. The device includes a first spreader for spreading at least one input signal with quasi-orthogonal codes, a second spreader for spreading another input signal with Walsh codes, and a PN (Pseudo-Noise) spreader for complex-spreading output signals of the first and second spreaders with PN sequences. The quasi-orthogonal codes are characterized in that a partial correlation value with the Walsh codes does not exceed a lowest partial correlation limit value.

摘要： A device and method for outer-loop power control in a discontinuous transmission mode in a CDMA mobile communication system. In an outer-loop power control method for a non-frame data transmission period of a dedicated control channel (DCCH) which transmits frame data discontinuously, the signal-to-noise ratio (SNR) of power control bits (PCBs) received at a mobile station from a base station is measured for the frame period, and it is determined whether the frame has errors based on the measured SNR. A closed-loop power control threshold is increased if a frame error exists and decreased if no frame errors exist.

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.
