Data multiplexing method and data multiplexer, and data transmitting method and data transmitter

Abstract

An effective data multiplexing method wherein an error correction ability is exerted at the maximum so that data transmission quality is improved and a data transmitting method in which an interleaving process applicable to data transmission using interpolation pilot signal is performed are provided. The data multiplexing method includes the steps of: coding input data for each input channel; multiplexing said data which is coded; performing an interleaving process on said data which is multiplexed; and outputting said data. In the data transmitting method, when an interleaving process is performed, an interleaver is used in which the number of columns of the interleaver is twice as many as the number of slots of a frame.

1 . A receiving method comprising steps of:
 receiving symbols arranged in slots in a frame;   reading out at least a portion of the received symbols from a slot in the frame;   storing in memory the read out symbols in a plurality of groups, each group having F symbols, wherein F is N times a number of the slots in said frame and N is an integer larger than 1, wherein the storing step includes respectively storing the read out symbols at a same predetermined position in each group so that one read out symbol is stored in each group; and   repeating the reading out and storing steps until all of the symbols in the frame are stored in the memory.   
   
   
       2 . The method of  claim 1 , further comprising:
 decoding the symbols stored in the memory.   
   
   
       3 . The method of  claim 1 , further comprising:
 determining each predetermined position according to a predetermined rule.   
   
   
       4 . The method of  claim 1 , further comprising:
 reading out the stored symbols from said memory group by group into a frame.   
   
   
       5 . A receiving method comprising:
 receiving symbols arranged in slots in a frame;   reading out at least a portion of the received symbols from a slot in the frame;   step for storing in memory the read out symbols in a plurality of groups, each group having F symbols, wherein F is N times a number of the slots in said frame and N is an integer larger than 1, wherein the storing step includes respectively storing the read out symbols at a same predetermined position in each group so that one read out symbol is stored in each group; and   repeating the reading out and storing steps until all of the symbols in the frame are stored in the memory.   
   
   
       6 . The method of  claim 5 , further comprising:
 a step for decoding the symbols stored in the memory.   
   
   
       7 . The method of  claim 5 , further comprising:
 a step for determining each predetermined position according to a predetermined rule.   
   
   
       8 . The method of  claim 5 , further comprising:
 a step for reading out the stored symbols from said memory group by group into a frame.   
   
   
       9 . A receiver, comprising:
 a wireless interface configured to receive symbols arranged in slots in a frame and read out at least a portion of the received symbols from a slot in the frame; and   a deinterleaver having a memory configured to store the read out symbols in a plurality of groups, each group having F symbols, wherein F is N times a number of the slots in said frame and N is an integer larger than 1,   wherein the deinterleaver is configured to control the storing of respective of the read out symbols at a same predetermined position in each group so that one read out symbol is stored in each group, and to repeatedly read out and control storing of the symbols until all of the symbols in the frame are stored in the memory.   
   
   
       10 . The receiver of  claim 9 , further comprising:
 a decoder configured decode the symbols stored in the memory.   
   
   
       11 . The receiver of  claim 9 , wherein the deinterleaver is configured to determine each predetermined position according to a predetermined rule. 
   
   
       12 . The receiver of  claim 9 , further comprising:
 reading out mechanism configured to read out the stored symbols from said memory group by group into a frame.
