摘要： A received symbol sequence is very accurately restored in a highly efficient manner with a simple configuration, wherein, respective bits of an information bit sequence are inputted to a cyclic register composed of the same number of registers as the number of bits of the information bit sequence. Signals read from the cyclic register are processed to generate a plurality of symbols. The processing is repeated each time the respective bits of the information bit sequences are shifted to the next registers, until the respective bits shift all over the registers for one cycle. All symbols generated by the process are transmitted as a symbol sequence. Symbols of a received symbol sequence are respectively inputted to a first register group composed of the same number of registers as the number of symbols of the symbol sequence. Respective symbols in each of a plurality of assumed symbol sequences, prepared in accordance with the number of bits of the information bit sequence are inputted to a second register group composed of the same number of registers as the number of registers in the first register group. Respective output signals read from the respective registers in the first and second register groups are processed to calculate correlation values, and the information bit sequence is restored based on the assumed symbol sequence from which the largest correlation value is derived.

摘要： The subscriber terminal ms sends the demand including at least information for identifying the demand subscriber terminal, information for identifying the requested information, and information relating to the urgency of the requested information to the information distribution transmission center HE through an going-up line. The information distribution transmission center HE plans a transmission schedule of the information to be transmitted based on the demand from the subscriber terminal ms, and transmits the transmission schedule information included in the down-going control data to the subscriber terminal which sent the demand prior to the actual transmission, and transmits the requested information according to the above-mentioned transmission schedule. The subscriber terminal ms receives and analyzes the down-going control data from the information distribution transmission center HE and is informed of the transmission schedule, and acquires the information to be transmitted based on the obtained transmission plan, stores the acquired information in a large scale memory, and reads the information from the memory means for use. A video on-demand system can be realized without introducing a large scale system such as video server and with a relatively small investment, and the centralization of traffic is mitigated, and the network resource is used efficiently.

摘要： An input signal composed of a predetermined total number of symbols is supplied to a series circuit of delay units. The input signal and delayed output signals from the delay units are multiplied by coefficients, and the products are added into an equalized output signal. The supplied input signal is transmitted, successively in normal, opposite, and normal directions, through a predetermined number of delay units corresponding to a unit number of symbols which is smaller than the predetermined total number of symbols to delay the input signal successively with those delay units. Each time the input signal is transmitted in the series circuit in one of the directions, an amplitude error of the equalized output signal is detected. In order to minimize the amplitude error, coefficients by which to multiply the input signal and the delayed output signals are calculated depending on the detected amplitude error. Alternatively, the input signal is divided into a plurality of blocks each composed of a predetermined number of symbols, and supplied to the series circuit to produce an equalized output signal of each of the blocks. An error signal is calculated which is composed of the sum of squares of differences between the equalized output signals and a reference signal. The coefficients are calculated depending on the rates of change of the error signal relative to the coefficients.

摘要： Upon transmission, when the digital transmission mode is set, an analog audio signal is A/D converted, the digital audio signal is coded, a first carrier is modulated by the coded signal and multiplied by a first multiplier, and the multiplied signal is sent to an orthogonal modulating and D/A converting circuit. When the analog transmission mode is set, a second carrier is modulated by the digital audio signal and multiplied by a second multiplier, and the multiplied signal is sent to the orthogonal modulating and D/A converting circuit. A signal of a frequency which is equal in both of the digital transmission mode and the analog transmission mode is given to the orthogonal modulating and D/A converting circuit. Upon reception, when the digital transmission mode is set, an output of an A/D converting and orthogonal demodulating circuit is frequency divided by a first frequency divider and demodulated and decoded. When the analog transmission mode is set, the output of the A/D converting and orthogonal demodulating circuit is frequency divided by a second frequency divider and demodulated. A frequency of a reference frequency signal is set to a common multiple of a coding rate of the A/D converter, the frequency of the first carrier, and the frequency of the second carrier, so that a necessary signal of each section can be easily formed from an output of a reference frequency signal generator.
