Abstract: PROBLEM TO BE SOLVED: To send an information signal in terms of a plurality of antenna beams without high frequency switching and cable wiring by using a transmitter subassembly so as to apply frequency conversion to any of FDM signals subject to frequency division multiplex and setting at least any of information including signals to a prescribed conversion frequency band. SOLUTION: A controller 130 of a base station gives an information including signal received from a PSTN to a radio equipment in the inside of a radio equipment assembly 104. The information including signal is modulated in the inside of the assembly 104, frequency-converted and combined into one FDM signal SFDM on an FDM cable 110. The frequency division channels in the inside of the FDM signal are assigned dynamically to each information including signal under the control of the base station controller 130. The one FDM signal SFDM on the FDM cable 110 carries a plurality of information including signals through a plurality of FDM channels.

Abstract: PROBLEM TO BE SOLVED: To obtain a device for a CDMA network which transmits and receives at a variety of data rates by connecting a 1st spread signal at a 1st rate and a 2nd spread signal at a 2nd rate. SOLUTION: A transmitter 600 clocks data again by performing time multiplexing of an orthogonal Walsh code (spread spectrum code) that corresponds to a slow rate and a fast rate and accomplishes rate conversion. Also, it has a rate converter 620 which buffers data received from a fast rate source 610 and a clock 630 which clocks again. The converter 620 is synchronized with what is selected by a switch 640 with orthogonal Walsh codes (corresponding to low and fast rates) wkL and wkU. An output of the converter 620 shows two pieces of different bit periods, and the codes wkL and wkU are used to multiply data by a multiplier 650.

Abstract: PROBLEM TO BE SOLVED: To select a proper transmission line based on signal amplitude, signal interference and multiple-path distortion by providing plural input ports and plural output ports to the distributer and connecting one input port to a corresponding output port of a 1st array so as to utilize a directivity beam antenna. SOLUTION: Each Butler matrix 12 of a mutli-layer integrated antenna array 120 has four input ports 14 and four output ports 16, 18. The input ports 14 are decoupled from the other input ports 14 so that no specific loss is caused even when input signals are coupled at the same frequency band. The Butler matrix 12 is so configured that a signal applied to one input port 14 is equally distributed to all the output ports, and each signal at each output port has a same amplitude substantially but phases of the outputs differ from each other. The input ports 14 of the matrix are coupled with a cross network 20 via a hybrid coupler 22.

Abstract: Disclosed is a multiple-beam transmitting system (100) for use in a wireless telecommunication system, including a radio transmitter assembly (104), which can be situated at the bottom of a base station tower, and a transmitter subassembly (102) that can be situated atop the base station tower. The radio transmitter assembly is operative to modulate and frequency translate a plurality of input information-bearing signals. The signals are then combined to form a first FDM signal, which can then be routed to the transmitter subassembly via a single FDM cable (110) running up the tower. The transmitter subassembly (102) includes a power splitter (120) for splitting the first FDM signal into a plurality of second FDM signals and a plurality of frequency translators, (T1 to TM ), each for frequency translating one of the second FDM signals. Each frequency translator thereby places at least one of the information-bearing signals within a predetermined translated frequency band. A multiple-beam-antenna (150) radiates a plurality of antenna beams, with each antenna beam transmitting at least one of the information-bearing signals placed by an associated frequency translator within the translated frequency band. A multiple beam receiving system can be employed to receive incoming signals from wireless terminals.

Abstract: A CDMA communication system is disclosed offering a near continuum of data rates up to a maximum rate. The disclosed CDMA communication system increases the data rate variability, without disturbing the orthogonality between users. An increased number of data rates is obtained by time multiplexing the data rates achievable with conventional CDMA systems to provide additional data rates for various multimedia applications. If a user is assigned a specific orthogonal code sequence, such as a Walsh sequence, which permits a maximum data rate, nR, with conventional systems, the user can obtain additional desired data rates up to the maximum rate nR, by time multiplexing the specific orthogonal code set. Desired bit rates are achievable for applications requiring bit rates that are not an integer multiple of the rates provided by conventional techniques. A fundamental rate of R or "fat pipe" rates of powers-of-two multiples of the fundamental rate can be achieved in a conventional manner. A desired rate up to the maximum "fat pipe" rate is achieved by time multiplexing the codes wn_k to achieve rates between R and nR, where wn_k, denotes the first nth of the spread spectrum code wk. The transmitter of the present invention achieves a rate conversion to match the appropriate codeword to the appropriate data rate, by employing buffering and reclocking of the data, with time multiplexing of the orthogonal Walsh codes corresponding to the available lower and upper rates. The rate conversion must be synchronized with the selection of the orthogonal Walsh code (corresponding to the lower and upper rates).
