摘要： The present invention provides a wireless LAN system which allows each slave communication device to perform wireless telephone communication by itself through a host station without relaying through a master communication device while a single wireless telephone line is used, and does not require particular processing such as authentication on the host station side. Each transmission/reception means 5 is controlled to switch between a first state in normal times in which a transmission/reception means 5 of a master communication device 1 is turned on and transmission/reception means 5 of respective slave communication devices 2 are turned off and a second state at the time of control delegation in which, in association with occurrence of a control delegation reason to any slave communication device, the transmission/reception means 5 of the master communication device 1 is turned off and only the transmission/reception means of the predetermined one slave communication device of the respective slave communication devices is turned on, and when a control delegation reason to any slave communication device occurs in the first state, a control delegation signal for permitting the transmission/reception means of that slave communication device to be turned on is transmitted from the master communication device 1 to that slave communication device through the respective short-range wireless communication means 4 to perform switching to the second state.

摘要： A (direct-sequence code division multiple access) DS-CDMA cellular system includes a plurality of cells each having one base station and a plurality of mobile stations. A signal transmitted form the base station is distinguished by a long code which is different from the others being uniquely allocated to each cell. A long code synchronization timing being detected by a correlation using a common short code. The long codes are searched in each mobile station by a partial correlation in a timing according to the long code synchronization timing. The partial correlation is a correlation between a signal received and a segment of a code defined by a part of the long code, the part being shifted in the long code. Further, the long codes are classified into a plurality of long code groups defined by long code group identification codes. A delay profile of the long code group identification code is detected and is compensated in fading according to said short code. Then, the long code group identification code is combined by rake combining, and is demodulated.

摘要： A plurality of sets of spreading code sequences are stored in registers. In case of soft hand-over, multi-code and long-delay paths, it is possible that the correlation peaks derived by the different PN sequences overlap. The spreading code sequences then are shifted by the generator registers in order to separate the peaks by one or more chips.

摘要： Power supply sockets of a distributing system of interior power supply wiring are provided with a communication distributing terminal, and apparatus (A1-An) are provided with a terminal unit 2 for connection to a communication line CL. A unique address is assigned for the terminal unit 2. A communication line CL is provided with a timing clock supply line TL, a unique address communication line AL, and a local area network (LAN) line LL, thereby connecting the apparatus (A1-An) connected to the power supply socket to the communication line CL. The unique address of the terminal unit 2 connected to the communication line CL is transmitted to the unique address communication line AL, and communication with the terminal unit 2 is controlled through the LAN line LL by the communication control unit 1. The terminal unit 2 transmits its own unique address to the unique address transmission line AL during a predetermined address registration period, when it failed to find its own unique address in unique addresses transmitted from the communication control unit 1. Thereby realizes very easy communication between the apparatus (A1-An).

摘要： A receiver having an enhanced cell search accuracy of three-step cell search. The receiver comprises a matched filter (MF) to which a received signal Sin is inputted and a sliding correlator unit (SC). The matched filter (MF) calculates the correlation between the received signal Sin and a first synchronization code PSC. The output Spsc is held in a memory (MEM1) and thereafter processed by a timing detecting part (TDP). The sliding correlator unit (SC) comprises sliding correlators (SC1 to SCq). The outputs (A[1] to A[q])are held in a memory (MEM2) and thereafter processed by a timing group identifying part (TGI). The sliding correlator unit (SC) calculates correlation by using first and second synchronization codes or only the first synchronization code. When using the first and second synchronization codes, the sliding correlator unit (SC) performs channel inference and phase correction and performs common-mode addition. When using only the first synchronization code, it performs only common-mode addition.

摘要： A 3-step cell search type receiver apparatus with an improved accuracy is provided. The receiver apparatus comprises a matched filter MF and sliding correlator unit SC to which a reception signal Sin is inputted. The matched filter MF computes correlation between the reception signal Sin and a primary synchronization code PSC and produces an output Spsc, which is retained in a memory MEM1 and then processed by a timing detection unit TDP. The sliding correlator unit SC comprises a plurality of sliding correlators SC1 to SCq, whose outputs A [1] to A [q] are retained in a memory MEM2 and then processed by a timing group identification unit TGI. The sliding correlator unit SC computes correlation based on the primary and secondary synchronization codes or the secondary synchronization code. In the former case, inphase-addition is performed after performing channel estimation and phase correction, and in the latter case, only inphase-correction is performed.
