    • There is provided a data communication apparatus and method in a multi-carrier CDMA communication system. A transmitting device determines whether a supplemental channel is transmitted. If the supplemental channel is transmitted, the transmitting device assigns the supplemental channel to each of all FAs having different carrier frequency bands and the other channels including a fundamental channel, a dedicated control channel, and a common control channel to one of the FAs. A receiving device determines whether the supplemental channel exists in input channel signals. If the supplemental channel exists, the receiving device despreads supplemental channel signals in each of the FAs, connects the despread supplemental channel signals to a supplemental channel decoder, despreads the other channels in one of the FAs, and connects the other channel signals to corresponding channel decoders.
    • 提供了一种在多载波CDMA通信系统中的数据通信装置和方法。 发送装置确定是否发送补充信道。 如果发送补充信道,则发送设备向具有不同载波频带的所有FA分配补充信道,并且向FA中的一个分配包括基本信道,专用控制信道和公共控制信道的其他信道。 接收装置确定补充信道是否存在于输入信道信号中。 如果补充信道存在,则接收设备对每个FA中的补充信道信号进行解扩,将解扩补充信道信号连接到补充信道解码器,对其中一个FA中的其他信道进行解扩,并将其它信道信号连接到相应信道 解码器

    • There is provided an encoding apparatus and method in a CDMA communication system. To encode input information of a k-bit sequence and generate a codeword with length N>(2k−1), an encoder encodes the input information using an (r, k) simplex code and generates a sequence of code symbols of length r (r=2k−1), a repeater repeats the sequence of code symbols t times ( t = ⌊ N r ⌋ + 1 ) , and a puncturer performs puncturing A times (A=rt−N) on the t repeated code symbol sequences so that the resulting codes have length N. The punctured symbols are distributed uniformly across the repeated code symbol sequences or confined to the tth repeated code symbol sequence.
    • 提供了一种CDMA通信系统中的编码装置和方法。 为了对k位序列的输入信息进行编码并生成长度为N>(2≤K≤1)的码字,编码器使用(r,k)单码进行编码,并产生 长度为r(r = 2K-1)的码符号序列,中继器重复码元序列t次 t = N r + 1 对t个重复码符号序列进行A次打孔(A = rt-N),使得所得到的码具有长度N.穿孔符号均匀地分布在重复的码符号序列上或限于第t / 重复代码符号序列。
