摘要： A direct spread spectrum communication system in accordance with a delayed multiplex mode in which improvement in correlation and improvement in error rate can be perfectly realized in any data length. A data generating section (2) has means for appending an additional bit so as to generate an integral multiple of the multiple number in generating information to be transmitted from data received from an upper layer (1) referred to as a MAC layer. This means learns the symbol length of a data part from information obtained from the upper layer (1), and knows the symbol length of a bit synchronization section, a frame synchronization section and a various information section which should be originally appended as a packet. Therefore, the number of additional bits such that the total number of symbols amounts to an integral multiple of the multiplex number is added before the frame synchronization section. A bit addition section may be inserted before the start of data entry, or at the last part of the data, that is, a lost part.
