METHOD FOR CODING USING POLAR CODE BY RADIX-4

摘要

PURPOSE: A coding method using a polar code based on radix 4 is provided to improve an operation speed by using a 4×4 base matrix structure. CONSTITUTION: A coding method uses a polar code based on radix 4. An input signal is encoded by using a 16×16 polar code based on the radix 4. The 16×16 polar code is based on a 4×4 base matrix structure. An expanded 16×16 base matrix is generated by expanding the 4×4 base matrix structure. The 16×16 polar code is generated by multiplying the expanded 16×16 base matrix with a bit reverse matrix. The coding method improves an operation speed comparing to the encoding speed using a polar code based on radix 2 proposed by Arikan.
