Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for providing variable rate data in a communications system using statistical multiplexing. SOLUTION: This invention discloses the variable rate transmission system wherein when the capacity of a traffic channel is equal to or more than a data rate of a packet, the packet of variable rate data generated by a variable rate data source (20) is modulated on the traffic channel by a traffic channel modulator (30). When the capacity of the traffic channel is smaller than the data rate, the packet of variable rate data is modulated onto the traffic channel by the traffic channel modulator (30) and modulated onto at least one overflow channel by a traffic channel modulator (32).

Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for providing high speed data communication in a cellular environment. SOLUTION: Adjacent cells, of the cellular system, 1 and 2A-2F are prevented from simultaneously transmitting data. Because the noise from transmission of adjacent cells is a primary source of interference, the transmission rate of power limited base stations 1-3 can be dramatically increased when the noise from adjacent cells is eliminated. The transmissions to each subscriber station 6 are made at a fixed transmission power level. However, the data rate of transmitted signals differs from one subscriber station 6 to another depending the path loss differences. In a first exemplary embodiment, the data rate of transmissions to the subscriber station 6 is determined by selecting an encoding rate for the transmitted signal while holding the symbol rate constant. In a second exemplary embodiment, the data rate of transmission to the subscriber station 6 is determined by selecting a modulation format for the transmitted signal which directly changes the symbol rate of transmission to the subscriber station 6.

Abstract: PROBLEM TO BE SOLVED: To provide a system for transmitting high-rate digital data under the presence of a multi-path state.
SOLUTION: In an orthogonal frequency division multiplexing (OFDM) communication system which uses an external Reed-Solomon encoder 22, an outer interleaver 24 and an inner convolution encoder 26, after inner convolution encoding, data bits are interleaved by an inner bit interleaver 28, and then are grouped into symbols, with each symbol having "m" bits. After grouping, the symbols are mapped to a complex plane by using quadrature amplitude modulation (QAM). Thus, bits, rather than symbols, are interleaved by the inner bit interleaver 28. A receiver performs soft decisions, regarding the value of each bit in each complex QAM symbol received.

Abstract: PROBLEM TO BE SOLVED: To increase pilot energy, to estimate the phase of communication signals and to perform tracking by modulating a digital data symbol relating to M by using at least two orthogonal modulation symbols of a length (n) including one or more Walsh functions. SOLUTION: M is equal to the product of the total number of orthogonal functions used at the time of generating the product of the functions and the modulation symbol used so as to generate respective individual symbols. The product of the function and a coefficient is selected so as to make M smaller than 64. Modulation symbol output for performing transmission is generated corresponding to the binary value of an input data code symbol. At least one, normally two, orthogonal function generator supplies the first and second orthogonal functions of the length (n). A selector or a selection means receives a user data symbol and the first and second functions, outputs the first orthogonal function when the symbol is the value of 1 and the second orthogonal function when it is the value of 2 and responds to the binary value of the data symbol.

Abstract: PROBLEM TO BE SOLVED: To provide a new and improved method and its device for formatting transmission vocoder data, non-vocoder data and signaling data. SOLUTION: The method and the device are the ones for constituting various types of data into a format with an original structure for transmission by various rates. Data for a transmission format can be voice data supplied by a vocoder (14) or a different type secondary traffic. Data made into a structure with a prescribed time periodical frame is transmitted by a microprocessor (18). A data frame is made into a structure to be one of some data rates in accordance with data. Vocoder data is supplied by one of the rates by the vocoder (14) and made into a structure by the frame in accordance with a prescribed format. The frame is formatted to be the fastest frame data rate while sharing vocoder data having non-vocoder data. The different type non- vocoder data can be made into a structure to be the fastest frame data rate. Additional control data is supplied to the data frame and, then, is useful for the various aspects of recovery in the case of transmission and reception.

Abstract: In an orthogonal frequency division multiplexing (OFDM) system (10) which uses an outer Reed-Solomon encoder and interleaver (24) and an inner convolutional encoder (26), after the inner convolutional encoding the data bits are interleaved by an inner interleaver (28), and then grouped into symbols, each symbol having 'm' bits. After grouping, the symbols are mapped to a complex plane using quadrature amplitude modulation (QAM). Thus, bits, not symbols, are interleaved by the inner interleaver (28). A receiver (12) performs a soft decision regarding the value of each bit in each complex QAM symbol received.
