rsc_encode.m

经典turbo码的编码过程该文件夹中的SC_TurboIC_MIMO_0524.m是将我turbo的编译码模块替换原来B3G系统中的turbo编译码模块而重新得到的. 定点仿真得,在比特信噪比&gt

function  [x,y]= rsc_encode(u,size,Mem)

output_matrix =zeros(4,2);
output_matrix =[0,1;0,1;1,0;1,0];
  
nextstate_matrix = zeros(4,2);
nextstate_matrix = [0,2;2,0;3,1;1,3] ;
 
tail_bit = zeros(1,4);
tail_bit = [0,1,1,0];

state=0;

for i=1:size-Mem
	x(i) = u(i);
	y(i) = output_matrix(state+1,u(i)+1);
	state = nextstate_matrix(state+1,u(i)+1);
end	

for i=size-Mem+1:size
	x(i) = tail_bit(state+1);
	y(i) = output_matrix(state+1,x(i)+1);
	state = nextstate_matrix(state+1,x(i)+1);
end
