    摘要： A time slot which is formed by time-division multiplexing is divided into a plurality of blocks in at least a frequency direction, and also within each one of said plurality of blocks a plurality of subcarriers are formed. A predetermined number of plurality of blocks forms one communication channel, whereby a plurality of communications are formed within a time slot. With this, one time slot can be multiplexed by communication of multiple carriers separated in frequency. In this manner, with simple constitution, communication can be performed satisfactorily even in an environment where a multiple path is present.

    摘要： A digital signal transmission method in which a digital signal having a header block of a predetermined length is transmitted. The header is comprised of a synchronization signal and auxiliary data. The auxiliary data is made up of first data or second data and a redundant error detection code. The redundant code indicates whether the block contains the first data as the auxiliary data or the second data as the auxiliary data so that different headers having different contents can be distinguished by the reproduction apparatus.

    摘要： In a recording/reproducing apparatus, having an analog-to-digital converter used in a recording mode and a digital-to-analog converter used in a reproducing mode; a digital filter comprises memories for storing first and second multiplication coefficient groups which provide predetermined filter characteristics and are in interpolated relation to each other; and, in the recording mode for first-and second-channel signals, the first and second multiplication coefficient groups are used for the first-and second-channel signals, respectively, and, in the reproducing mode, the second-and first-multiplication coefficient groups are used for the first-and second-channel signals, respectively. In recording and reproducing modes for a single-channel signal, the first and second multiplication coefficient groups are alternately used for successive samplings.

    摘要： A method of error correcting pulse code modulated data is provided in which the data words and check words are encoded in an error correcting block. The encoded data words may have one of at least two error conditions associated therewith, and the presence of each type of error condition is detected for each word. A corresponding pointer identifying one of these error conditions is added to the data words. In subsequent processing, the kinds of pointers added are discriminated, and the data words are processed on the basis of the results of this discrimination to correct or compensate for error conditions in the data words.
