Web24 apr. 2024 · When multiple user devices in a cell share the same ZC sequence, a cyclic shift is used specific to each user device in order to keep signal orthogonality. The cyclic shift is calculated or, in other words, quantised based on various inputs. 2. Main request - claim 1 - Article 84 EPC. Web101: a right shift in the bits of this codeword will give 110. 011: right shifting of these bits will provide 101. Hence, it is clear that shifting the bits of the codewords gives rise to another codeword thus cyclic shifting property is verified. Codes that follow both linearity, as well as cyclic shifting, are called cyclic codes.
