摘要： A demodulator for code-division multiple-access spread-spectrum communications stores received chip data in a separate memory area for each transmitting station. Each area has a capacity of at least two symbols. When a complete symbol is received from a transmitting station, all chip data stored in the corresponding memory area are correlated with the corresponding spreading code, and estimated symbol values are derived from the correlated values. The correlated or estimated value of the oldest symbol is output as a demodulated value. The difference between each estimated symbol value and the previous estimate for the same symbol is multiplied by the spreading code to generate remaining interference values, which are subtracted from all chip data stored in memory areas for other transmitting stations, thereby updating those data.

摘要： To initiate communication, a first station generates a synchronization signal and sends the synchronization signal to a second station. When the second station detects the synchronization signal, the second station acquires synchronization and sends a synchronization-acquisition message back to the first station. The first station now reduces the power of the synchronization signal, while continuing to send the synchronization signal, and also begins sending a modulated data signal. The second station uses the synchronization signal to maintain synchronization for demodulating the data signal.

摘要： A spreading code generator generates a spreading code by modulo-two addition of two internal spreading codes. The first internal spreading code is part of a pseudorandom noise sequence, created by resetting a pseudorandom noise generator to an assigned initial state at intervals determined by counting a framing signal. The second spreading code is selected from a set of preferably orthogonal sequences, the selected sequence being repeated at intervals shorter than the period of the framing signal. A code-division multiple-access communication system employs this spreading code generator to generate all spreading codes used at all communicating stations. One of the spreading codes generated at each station is transmitted as a synchronization signal.

摘要： There is disclosed a spread code generation device for spread spectrum communication wherein an input data is modulated so as to be spread by a spread code having a first period. The device includes a long period PN code generator for generating a spread code having a second period longer than the first period, an initial state register for storing an initial phase of the spread code having the first period output from the long period PN code generator and for outputting the initial phase to the long period PN code generator, and a counter for receiving and computing the spread code output from the long period PN code generator and for outputting a trigger signal to the initial state register when the computed spread code reaches the first period. The initial state register outputs the initial phase to the long period PN code generation in response to the trigger signal from the counter. The long period PN code generator is reset to the initial phase when the initial phase is input to the long period PN code generator, whereby the spread code having the first period is output from the counter.

摘要： A three-dimensional image generator generates a random signal which it filters in two dimensions generate a realistic three-dimensional image of a natural object such as ocean waves or clouds. By performing the filtering operation repeatedly on overlapping intervals of the random signal, related images can be obtained to generate moving scenes at real-time rates. Two or more partial image generators can be connected in parallel to generate different directions of motion, or different parts of a complex scene. Within each partial image generator, two or more space filters can be connected in parallel to generate superimposed patterns, such as small ripples superimposed on large waves. This image generator is much faster than previous, fractal image generators.

摘要： In a mobile radio communication system, at a transmitter side, when a sound-absent section is detected in sound data, transmission of the sound data is stopped, and instead, tail bits are transmitted. A transmission power is lowered to 0 (zero) or a given value other than 0 when the transmission of the tail bits is finished. The lowering of the transmission power is held until a sound-present section is detected. Convolutional encoding is effected to the sound data and the tail bits prior to transmission. At a receiver side, the variation in transmission power is monitored to control an operation of an associated component in response to the monitored power variation. Viterbi decoding is effected for decoding the convolutional code.
