Claim 2:
3. The method of claim 1, wherein the sequentially selecting the bit sequence of the specified length from the circular buffer comprises:
sequentially selecting bits in an ascending or descending order of indexes starting from the position of P0=N−M in the circular buffer responsive to the code rate of the Polar code encoding being less than or equal to the predefined threshold, or starting from the starting bit position of the encoded bit sequence in the circular buffer responsive to the code rate of the Polar code encoding being greater than the predefined threshold,
reading from the position of P0=N−N in the circular buffer responsive to the code rate of the Polar code encoding being less than or equal to the predefined threshold, or from the starting bit position of the encoded bit sequence in the circular buffer responsive to the code rate of the Polar code encoding being greater than the predefined threshold, to a first end of the encoded bit sequence in the circular buffer, and
continuing the reading from a second end of the encoded bit sequence in the circular buffer until the bit sequence of the specified length is read.
