Abstract: A system for rapidly acquiring a spreading code, used in a code division multiple access (CDMA) system, comprises a generator for generating a first long code and a second long code, with each long code having a length of N chips. The first long code is different from the second long code. A transmitter transmits the first long code and the second long code at a first phase angle and at a second phase angle, respectively, on a carrier signal over a communications channel using radio waves. The first long code and the second long code may be transmitted at an in-phase (I) angle and at a quadrature-phase (Q) angle, respectively, on the carrier signal. From the communications channel, an I acquisition circuit and a Q acquisition circuit may acquire, in parallel, the first long code and the second long code from the I angle and the Q angle, respectively, of the carrier signal by searching, in parallel, N/2 chips of the first long code and the second long code.

Abstract: An apparatus and method for adjusting a desired expression section according to input bit values in a mobile communication system that expresses only a defined partial section of the input bit values in order to make the number of output bits be less than the number of the input bits, and maps bit values included in unexpressed sections to a specific value is provided. In the apparatus and method, a measurer divides possible output bit values into at least three sections, and measures output frequencies of output bits for the respective sections for a predetermined time. A controller adjusts the desired expression section, when an output frequency for a specific section is greater than output frequencies for other sections.

Abstract: A method to process DP bits from multiple fingers within a WCDMA rake receiver is provided. DPCH pilot symbols are received, quantized and channel compensated. Then processing operations for individual fingers for the channel compensated quantized despread DPCH pilot symbols are chosen based on the DPCH slot format. The DPCH pilot symbols are processed based on the DPCH slot format in order to produce processed DPCH pilot symbols in a common format. These processed symbols may then be combined. Other embodiments may further allow for the computation of an SNR estimate based on the combined DPCH pilot symbols.
