摘要： A conventional packet frame includes a MAC header, one MAC service data unit (MSDU) and a frame FCS. This frame is repeated to send a plurality of MSDUs. A proposed packet frame includes a MAC header, a plurality of MSDUs and a frame FCS. A unique bit pattern is provided in the MAC header to distinguish the proposed packet frame from the conventional packet frame. Thus, the total data stream can be shortened.

摘要： A spreading code generating apparatus carries out M-sequence multiplication and zero value addition of generated orthogonal codes to obtain channel identification codes, and then carries out inverse Fourier transform of the channel identification codes to generate spreading codes and inverse spreading codes. A transmitting apparatus and a receiving apparatus store the spreading codes and the inverse spreading codes generated by the spreading code generating apparatus, respectively, and use a single code respectively selected from the stored codes to carry out spread spectrum communication. With the use of the spreading codes for spreading, the input signal is spread over a wide frequency band with uniform power on the frequency axis. Thus, transmission characteristics are improved, and multiplexing capacity is increased.

摘要： In serial transmission of a mixture of isochronous data and anisochronous data, communications through a transmission path with a high ratio of occurrence of transmission errors may disturb images during streaming reproduction and produce noise in sound. To solve this problem, the isochronous data that has not been successfully received is retransmitted by using an anisochronous region. Thus, a transmission error of the isochronous data can be reduced without impairment of isochronous characteristics of the data.
