Patent number: 10879952Abstract: Apparatuses and methods for decoding a spreading code-encoded signal. The decoder decodes a spreading code-encoded signal by performing a synchronization search to determine a synchronization point. The synchronization point defines a time delay for aligning a spreading code, which was used to generate the spreading code-encoded signal, with the spreading code-encoded signal. The synchronization search includes obtaining candidate results, where each candidate result is a decoding attempt that applies a time delay for aligning the spreading code with the spreading code-encoded signal. The synchronization search also includes determining the synchronization point by identifying the time delay corresponding to the candidate result that is associated with a power measurement that satisfies a synchronization search criterion. A decoder code synchronization is performed to align the spreading code with the spreading code-encoded signal, using the synchronization point.Type: GrantFiled: April 18, 2018Date of Patent: December 29, 2020Assignee: Huawei Technologies Co., Ltd.Inventors: Lan Hu, Xinyu Xu
