20100318875 | Data Transmission Method and Equipment - The present invention discloses a data transmission method and apparatus. The method comprises: segmenting data to be transmitted into information file segments with a length of Tb bits; performing forward error correction (FEC) coding for Tb information bit sequences composed of bits in same positions in a plurality of continuous information file segments to generate Tb check bit sequences, putting each bit of the check bit sequences in the same position in the check file segments as the corresponding information bit sequences; and transmitting each of the information file segments and check file segments according to their order; the number of bits contained in the information bit sequences being less than or equal to the maximum length of K | 12-16-2010 |
20110007661 | DEVICE AND METHOD FOR INTERLEAVED ENCODING RS CODE - The present invention provides a device and method for interleaved encoding RS code, the RS code used being RS (N, K, S). The method comprises: firstly, writing the data in the data packets to be RS interleaved encoded into the information region of the RS code byte interleaver column-by-column in turn; then, constructing the data of each row of the check region based on the data written into the information region; finally, performing cyclic shifting processing on the data of the check region, and reading out the data of the check region in the RS code byte interleaver column-by-column in turn. The present invention can be used to improve the performance of the entire data packet outputted, thereby enhancing the reliability of the data link layer, by evenly spreading the areas with a filled value of 0 in the last column of the information region that is filled with valid information and by performing cyclic shifting processing on the data of the check region so that the data of that region offer larger time span and good diversity effect when outputted. | 01-13-2011 |
20110041034 | Decoding Method and Device for Reed-Solomon Code - The present invention provides a decoding method and device for Reed-Solomon (RS) codes. The method includes the following steps: A: filling data to be decoded in a byte interleaver by column in turn; B: performing cyclic shift to data in a check region of the byte interleaver by row and/or by column, so as to make the data of each row in the check region become check data in sequence of data of corresponding row in an information region of the byte interleaver; C: performing RS decoding by row method, and writing information data of each row obtained after decoding into the corresponding row in the information region of the byte interleaver in turn; and D: reading business data of the decoded information data from the information region of the byte interleaver by column. The method and device of the present invention can achieve the best interleaving effect. | 02-17-2011 |
20110059764 | Transmission power control method and system for a physical uplink shared channel - The present disclosure provides a transmission power control method for a physical uplink shared channel, including: when there is only uplink control information but no uplink shared channel data sent over the physical uplink shared channel, the transmission power of the physical uplink shared channel is set according to the total number of bits contained in a channel quality indication signaling and its corresponding cyclic redundancy check as well as an amplitude offset. The present disclosure also provides a transmission power control system for a physical uplink shared channel. The method and system described in the present disclosure can ensure the overall performance of a system. | 03-10-2011 |
20120297266 | METHOD FOR PROCESSING FORWARD ERROR CORRECTION, FEC, DATA, DEVICE AND SYSTEM THEREOF - A method for processing Forward Error Correction, FEC, data, which includes: a sender encapsulates the FEC data to be a Transport Stream, TS, message, sets FEC identification information in the TS message, and encapsulates the TS message to be a Real-time Transport Protocol, RTP, message; then sends the RTP message to a terminal side. The reception end receives the RTP message; if the reception end has a function for FEC decoding, the reception end identifies the FEC data according to the FEC identification information in the TS message of the received RTP message, and recovers the missed media message according to the FEC data; if the reception end does not have the function for FEC decoding, the reception end processes the RTP message after removing the message header. The embodiments of the present invention also provide a transmission and processing device. | 11-22-2012 |
