    • A decoding apparatus and method are described. The decoder includes N successive decoder groups numbered 1 to N arranged in series. Each decoder group includes primary decoding means for decoding the first sequence of codewords in combination with the source sequence of symbols to produce a sequence of primary decoded symbols; intermediate interleaving means for interleaving the sequence of primary decoded symbols using intra-block permutations on the source sequence of symbols and inter-block permutations on each intra-block permuted block across the predetermined number of the intra-block permuted blocks to produce a sequence of intermediate symbols; secondary decoding means for decoding the second sequence of codewords in combination with the sequence of intermediate symbols and a sequence of interleaved source symbols to produce a sequence of secondary decoded symbols; and de-interleaving means for de-interleaving the sequence of secondary decoded symbols to produce a sequence of estimated symbols.

    • An interleaver and method of interleaving operate on data represented in a sequence of symbols to produce an interleaved sequence of symbols. The interleaver performs intra-block and inter-block permutations on the sequence of symbols. An encoder and method of encoding operate on data represented in a source sequence of symbols. The source sequence of symbols is encoded into a first sequence of codewords and interleaved using intra-block and inter-block permutations to produce a sequence of interleaved symbols. The sequence of interleaved symbols is encoded into a second sequence of codewords. A decoder and method of decoding operate on data represented in a sequence of received symbols. The sequence of received symbols comprises a formatted copy of the source sequence of symbols and the first and the second sequence of codewords.

    • A method of acquiring a transmitted pseudo noise (PN) code c(t) from a received signal r(t) that is data modulated. The method includes, for a BPSK modulated signal, multiplying the received signal r(t) by cos(&ohgr;0t) and sin(&ohgr;0t), respectively to produce in-phase and quadrature (I-Q) down converted signals. Then multiplying the I-Q down converted signals by the PN code c(t), having a second PN code phase, to produce f(t) and g(t) respectively. Thereafter, summing separate contiguous portions of f(t) and g(t) and multiplying the summed portions of f(t) and g(t) by a matrix. The matrix represents data patterns within an interval MTc that spans the separate contiguous portions of f(t) and g(t). Lastly, the results of the matrix multiplication are compared to a threshold value to determine if the first PN code phase is equal to the second PN code phase.
    • 从被数据调制的接收信号r(t)获取发送的伪噪声(PN)码c(t)的方法。 对于BPSK调制信号,该方法包括分别将接收信号r(t)乘以cos(ωωt)和sin(ωωt)以产生同相和正交(I-Q)下转换信号。 然后将I-Q下变频信号乘以具有第二PN码相位的PN码c(t),以分别产生f(t)和g(t)。 此后,将f(t)和g(t)的分离的连续部分相加,并将f(t)和g(t)的相加部分乘以矩阵。 矩阵表示跨越f(t)和g(t)的分开的连续部分的间隔MTc内的数据模式。 最后,将矩阵乘法的结果与阈值进行比较,以确定第一PN码相位是否等于第二PN码相位。
