摘要： Positions holding different bit values between a first code word, which is obtained by coding an information bit sequence based on a coding method utilizing quasi-cyclic codes, and a second code word, which has the close Hamming distance from the first code word and satisfies a parity check of the coding method, are identified. Thereafter, a code word is generated by inserting bit values known to the transmitter and receiver into the identified positions of the information bit sequence and coding the information bit sequence. Upon reception of a signal based on the generated code word, the receiver judges whether known bit values held by corresponding positions in a code word obtained by decoding the received signal are the same as preset bit values. If the judgment result is negative, the code word based on the received signal is judges as erroneous even when it satisfies the parity check.
摘要翻译：在通过使用准循环码的编码方法对信息比特序列进行编码而获得的第一码字和第二码字之间保持不同比特值的位置与第一码字具有相近的汉明距离并满足识别编码方法的奇偶校验。此后，通过将发送器和接收器已知的位值插入信息比特序列的识别位置并对信息比特序列进行编码来产生码字。接收到基于所生成的代码字的信号时，接收机判断通过对接收到的信号进行解码而获得的码字中的相应位置所保持的已知比特值是否与预设比特值相同。如果判断结果为否定，则即使满足奇偶校验，基于接收信号的码字也是判断为错误的。

摘要： Provided is a communication method for improving the communication quality of multicast transmission. A grouping table storage section stores a grouping table in which Ack return order positions indicating priority orders of the reception terminals which each return an Ack, and addresses of the reception terminals are set. An Ack return order position notification frame creation section notifies each reception terminal of a corresponding Ack return order position based on the grouping table. An Ack return permission information determination section refers to the grouping table, determines the number of reception terminal that are to be permitted to return an Ack, and creates Ack return permission information in which information about the reception terminals that are to be permitted to return an Ack is set, based on the determined number of reception terminals. A multicast creation section creates a multicast containing the Ack return permission information and transmission data.
