Abstract: On the transmitting side a spread modulated signal that has undergone spread spectrum processing and an information modulated signal that has not undergone spread spectrum processing are multiplexed in a same frequency band. On the receiving side the specific modulated signal is first demodulatedby a spread spectrum demodulation section 1803, then a replica signal of the specific modulated signal is generated by a spread spectrum modulated signal regeneration section 1805, and the information signal that has not undergone spread spectrum processing is extracted by eliminating the replica signal from the multiplex signal. By this means, even when a large number of information signals are transmitted in a same frequency band, these signals can be separated and demodulated satisfactorily on the receiving side.

Abstract: A data processor selects a set of BOC correlations in accordance with a BOC correlation function for the sampling period if the primary amplitude exceeds or equals the secondary amplitude for the sampling period. The data processor selects a set of QBOC correlations in accordance with a QBOC correlation function for the sampling period if the secondary amplitude exceeds the primary amplitude for the sampling period. The data processor uses either the BOC correlation function or the QBOC correlation function, whichever with greater amplitude, at each sampling period to provide an aggregate correlation function that supports unambiguous code acquisition of the received signal.

Abstract: A wireless terminal is operable to receive a Wideband Code Division Multiple Access (WCDMA) signal from a base station and includes clock circuitry, a wireless interface, and a Primary Synchronization (PSYNC) module (708). The clock circuitry generates a wireless terminal clock using a wireless terminal oscillator. The wireless interface receives the WCDMA signal, which is produced by the base station using a base station clock that is produced using a base station oscillator that is more accurate than the wireless terminal oscillator. The PSYNC module includes a plurality of PSYNC correlation branches (808A-808N). Each PSYNC correlation branch phase rotates the WCDMA signal based upon a respective frequency offset (806), correlates the phase rotated WCDMA signal with a Primary Synchronization Channel (PSCH) code over a plurality of sampling positions (808), and produces PSYNC correlation energies based upon the correlations for each of the plurality of sampling positions (810).

Abstract: 무선 단말기는 클럭 회로, 무선 인터페이스 및 1차 동기(PSYNC: Primary Synchronization) 모듈로부터 광대역 코드 분할 다중 접속(WCDMA) 신호를 수신하도록 동작가능하다. 클럭 회로부는 무선 단말기 발진기를 사용하여 무선 단말기 클럭을 생성한다. 무선 인터페이스는 무선 단말기 발진기보다 좀더 정확한 기지국 발진기를 사용하여 생성된 기지국 클럭을 사용하여 이 기지국에 의해 생성되는 WCDMA 신호를 수신한다. PSYNC 모듈은 복수의 PSYNC 상관 브랜치들(correlation branches)을 포함한다. 각각의 PSYNC 상관 브랜치는 각각의 주파수 오프셋에 기초하여 WCDMA 신호를 위상 회전시키고, 복수의 샘플링 위치에 걸쳐 상기 위상 회전된 WCDMA 신호를 1차 동기 채널(PSCH: Primary Synchronization Channel) 코드와 상관 동작하고, 복수의 샘플링 위치들 각각에 대한 상관 결과들에 기초하여 PSYNC 상관 에너지 값들을 산출한다.

Abstract: PURPOSE: A device for estimating a frequency offset of a band spread signal and a method thereof are provided to minimize power consumption by estimating a frequency offset having high reliability with simple operation during the estimation of the frequency offset. CONSTITUTION: A frequency offset generating unit (104) generates and adds a frequency offset to a spread symbol-based signal in order to generate a frequency offset addition signal. The frequency offset generating unit converts the frequency offset addition signal into a complex number. A frequency offset estimating unit (105) estimates a frequency offset from the converted frequency offset addition signal. An evaluating unit (106) calculates average values about a square number of a difference between the frequency offset estimated by the estimating unit and an actual frequency offset. The evaluating unit evaluates the frequency offset estimation performance of the frequency offset estimating unit according to the variation between the average values.
