摘要:
A system and method for processing uncompressed high definition video data to be transmitted over a wireless medium is disclosed. In one embodiment, the system includes i) a plurality of convolutional encoders configured to input a plurality of video data streams and output a plurality of encoded data streams, respectively, wherein each data stream includes a plurality of data bits, ii) a group multiplexer configured to multiplex the plurality of encoded data streams into a multiplexed data stream, wherein the group multiplexer is further configured to multiplex a plurality of data bits together at one time and iii) a circulant bit interleaver configured to receive an m×n data stream block having n columns and m rows or convert the multiplexed data stream to an m×n data stream block, wherein the m×n data stream block comprises m×n data bits, and wherein the bit interleaver is further configured to interleave the received data bits diagonally and in a circulant manner with respect to the m×n block. The circulant bit interleaver interleaves the multiplexed data bits such that all data bits in one QAM symbol come from different convolutional encoders.
摘要:
A communication method includes causing a transmitter to apply error correcting or detecting code systems to multiple frames or packets and to transmit the multiple frames or packets in succession, causing a receiver to receive the transmitted frames or packets and to decode each of the frames or packets received, and causing the receiver to send an acknowledgment signal to the transmitter on the basis of the results of decoding of the frames or packets. The transmitter applies two or more error correcting or detecting code systems to the frames or packets.

PROBLEM TO BE SOLVED: To maintain the throughput of wireless communication even in an inferior environment of a channel. SOLUTION: A division means 1a of wireless communication equipment 1 divides data transmitted to a data area 3 of a frame format of a wireless signal into a plurality of segments. A coding means 1b codes the data 3a, 3b, ..., 3n segmented by the division means 1a in an unit of segments. The receiving means 2a of wireless communication equipment 2 receives a wireless signal of the frame format in which data of the data area 3 are divided into a plurality of segments. A decoding means 2b decodes the data 3a, 3b, ..., 3n of the wireless signal received by the receiving means 2a in an unit of segments. COPYRIGHT: (C)2010,JPO&INPIT
