Transmitter and method for transmitting data block in wireless communication system

摘要

Provided are a transmitter and a method for transmitting a data block in a wireless communication system. The method comprises the following steps: encoding an information bit and generating a block coded with an NCBPSS bit; generating two sub-blocks by parsing the coded block; and transmitting the two sub-blocks from the transmitter. By preventing the bits that are contiguous to the encoding block from having continuous identical reliabilities on a signal constellation, the deterioration of the decoding performance of the transmitter can be prevented.

1. A method of receiving a data block in a wireless communication system, comprising:
receiving two subblocks with index l=0, 1 from a transmitter, wherein the received codedblocks are parsed as shown:yk,l={x2⁢s·NES⁢⌊ks·NES⌋+l·s·NES+kmod⁡(s·NES),k=0,1,…⁢,⌊NCBPSS/(2⁢s·NES)⌋⁢s·NES-1x2⁢s·NES⁢⌊ks·NES⌋+2⁢s·⌊kmod⁡(s·NES)s⌋+kmods,k=⌊NCBPSS/(2⁢s·NES)⌋⁢s·NES,…⁢,NCBPSS2-1⁢⁢where⁢⁢s=max⁢{1,NBPSCS2}, NCBPSS is the number of bits per coded block, NBPSCS is the number of coded bits per subcarrier per spatial stream, NES is the number of encoders, └z┘ is the largest integer less than or equal to z, z mod t is the remainder resulting from the division of integer z by integer t, xm is the m-th bit of a block of bits, m=0 to NCBPSS−1, and yk,l is bit k of the subblock l.
