摘要： A system and method for data transmissions in a wireless communications system, which accommodates for a periodic blockage of the transmission signal, is provided. A data stream is segmented into packets of a predetermined fixed-size for a burst-mode transmission over a channel of the communications system, wherein the transmission is subject to a periodic blockage. A forward error correction outer code is then applied to the packets of the data stream for recovery of packets subjected to the periodic blockage, and a unique word is added to each packet for acquisition of frequency, carrier phase and symbol timing of the respective packet. The packets of the data stream are interleaved based on an interleaver of a depth based at least in part on a ratio of a blockage free duration between two consecutive blockages of the periodic blockage to a duration of each blockage of the periodic blockage.

摘要： An approach for encoding a physical layer (PL) header of a PL data frame is provided. The PL header comprises sixteen information bits u i , ( i = 0,1, 2, ... ,15), and the encoding is based on a convolutional code, whereby, for each information bit, five associated parity bits p i,k , ( k = 0, 1, 2, 3, 4) are generated, resulting in 80 codebits. The resulting 80 codebits are punctured to form a (16,77) codeword ( c 0 , c 1 , c 2 , ..., c 76 ). The codebits of the (16,77) codeword are repeated to generate a (16,154) physical layer signaling codeword ( c 0 , c 0 , c 1 , c 1 , c 2 , c 2 , ... , c 76 , c 76 ) for transmission of the PL data frame over a channel of a communications network. Further, for each information bit, each of the associated five parity bits is generated based on a parity bit generator, as follows: p i,k = ( u i * g k, 0 ) ⊕ ( S 0 * g k , 1 )⊕( S 1 * g k , 2 )⊕( S 2 * g k , 3 )⊕( S 3 * g k ,4 )⊕, where S 0 = u i -1 , S 1 = u i -2 , S 2 = u i -3 , S 3 = u i- 4 , and wherein generator polynomials for g k = ( g k ,0, g k ,1, g k ,2, g k ,3, g k ,4, ), are as follows: g 0 = (1,0,1,0,1); g 1 = (1,0,1,1,1); g 2 = (1,1,0,1,1); g 3 = (1,1,1,1,1); g 4 = (1,1,0,0,1).
