Patent ID: 11329671

Abstract:
A method for use in a wireless transmitter of interleaving coded bits includes: determining an integer number (M) of polar coded bits {e(0), . . . , e(M−1)} for wireless transmission; determining a smallest integer number (T) such that T(T+1)/2>=M; and determining a one-dimensional interleaving index array, interleavingId( ), that represents the column by column non-zero elements of a two-dimensional matrix. The two-dimensional matrix includes a hypothetical T by T matrix containing the polar coded bits {e(0), . . . , e(M−1)} input row by row without using the lower right corner elements of the T×T matrix. The method further includes: interleaving the polar coded bits {e(0), . . . , e(M−1)} using the one-dimensional interleaving index array resulting in the output sequence {f(0), . . . , f(M−1)} wherein f(i)=e(interleavingId(i)); and transmitting the interleaved polar coded bits to a wireless receiver.
