    摘要: A method for generating a training sequence code (TSC) in a communication system. The method includes obtaining a full set of training sequence code candidates through joint channel estimation with consideration of a symbol delay of an interfering signal; optimizing cross-correlation properties for the full set; obtaining a subset for necessary training sequence codes among the training sequence code candidates; defining each of training sequence codes in the obtained subset as a reference sequence; and generating optimized training sequence codes by copying symbols of a predetermined number of bits located in the front of the reference sequence, arranging the copied symbols in Most Significant Positions (MSPs) as a guard sequence, copying symbols of a predetermined number of bits located in the rear of the reference sequence, and arranging the copied symbols in Least Significant Positions (LSPs) as a guard sequence.

    摘要: A method for determining a bit pattern of a symbol in a wireless communication system using a cross modulation scheme. The method includes generating symbols with the cross modulation scheme, classifying positions of coding symbols by reliabilities of at least 3 classes according to an average bit error rate BER(ave) of symbols generated with the cross modulation scheme and a bit error rate BER based on transmission positions of the coding symbols in a modulation symbol during transmission of a packet with the cross modulation scheme, and determining a bit pattern such that higher-priority symbols are inserted into higher-reliability positions.

    摘要: A method of a server and an apparatus for establishing a social relationship between participants in a communication system providing an Immersive Social Centre (ISC) service are provided. The method includes generating information about a contacts group for at least two participants of a social service chat or session and a social relationship of the participants; notifying the generated information to at least one of the participants; and sending a social relationship setting request to at least one other participant of the at least two participants excluding the at least one of the participants notified of the generated information.
