Interleaving apparatus and method for symbol mapping in an HSDPA mobile communication system |
摘要 |
An interleaver separates an area of a buffer included therein into a first write area and a second write area according to a ratio of coded bits with higher priority to coded bits with lower priority, sequentially writes a stream of the coded bits with higher priority in a row direction from a first column to a last column among the columns in the first write area, and sequentially writes a stream of the coded bits with lower priority in a row direction from a first column to a last column among the columns in the second write area, and permutes the columns in the buffer area according to a given rule. A multiplexer divides rows in the buffer area into a first read area and a second read area having the same size, and alternately reads as many bits as a number determined based on a prescribed modulation technique from the first read area and the second read area in such a manner that the bits are sequentially read in a column direction from a first row to a last row among the rows of each of the first read area and the second read area, and multiplexes the read coded bits.
