Claim 0:
1. A receiving method comprising:
receiving a signal from a transmitting apparatus;
demodulating the signal to generate values based on 64-quadrature amplitude modulation (QAM);
splitting the values into a plurality of groups;
deinterleave the plurality of groups; and
decoding values of the deinterleaved plurality of groups based on a low density parity check (LDPC) code, a code rate of the LDPC code being 5/15 and a code length of the LDPC code being 16200 bits,
wherein the plurality of groups are deinterleaved based on a following equation:, Y
      
        π
        ⁡
        
          (
          j
          )
        
      
    
    =
    
      
        X
        j
      
      ⁢
      
        
      
      ⁢
      for
      ⁢
      
        
      
      ⁢
      
        (
        
          0
          ≤
          j
          <
          
            N
            
              g
              ⁢
              roup
            
          
        
        )
      
    
  
  ,

where Xjis a j-th group among the plurality of groups, Yj is a j-th group among the deinterleaved plurality of groups, Ngroup is a number of the plurality of groups, and π(j) denotes an interleaving order for the deinterleaving, and
wherein the π(j) is defined as follows:, The Interleaving Order
