Abstract
There is provided a signal receiving apparatus including first to pth stage computers configured to apply, in a step-by-step manner, butterfly operations to 2input values; and 2registers configured to store values obtained by a p−1th stage computer wherein the pth stage computer includes (a) 2butterfly operation circuits configured to transmit, from corresponding 2output ports, values obtained by the butterfly operations based on values provided to 2input ports and (b) 2selecting circuits arranged corresponding to the butterfly operation circuits, each selecting circuit providing a value of a register corresponding to different one of 2BFInOrder_i(j,t) (wherein, BFInOrder_i(j,t) denotes values obtained by converting BFOutOrder_i(j,t)=t+j*2+i*2or (2−1−t)+j*2+i*2) expressed by base H to base 2of (log2)−1 words, word-reversing the values converted to base 2, and converting the word-reversed values to the base H).
