Blockwise parallel frozen bit generation for polar codes

Abstract

An electronic device configured to perform polar coding is described. The electronic device includes a bit pattern generator (3403) configured to successively perform a bit pattern generation process over a series (t=┌n/w┐) of clock cycles; and a counter (c, 4203), operably coupled to the bit pattern generator (3403) and configured to count a number of successive bit pattern generation sub-processes over the series (t=┌n/w┐) of clock cycles. The bit pattern generator (3403) is configured to: provide a successive sub-set of (w) bits from a bit pattern vector (bk,n) in each successive t=┌n/w┐ clock cycle; where the bit pattern vector comprises n bits, of which ‘k’ bits adopt a first binary value and n−k bits adopt a complementary binary value.
