摘要： Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous Ethernet frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming Ethernet frames based on frame information extracted from previously received Ethernet frames. For example, a remote unit can be configured to receive one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next Ethernet frame. The remote unit can extract the payload data from the next Ethernet frame based on the predicted value for the additional start-of-frame field.

摘要： Fourier transform is performed on a reception signal to obtain a first calculation value. Fourier transform is performed on a known signal to obtain a second calculation value. The first calculation value is divided by the second calculation value to obtain a third calculation value. Inverse Fourier transform is performed on the third calculation value to obtain a fourth calculation value. A maximum value of an amplitude of the fourth calculation value and a sample point at which the maximum value is obtained are detected. The position of the known signal in the reception signal is detected from the sample point at which the maximum value is obtained.

摘要： Disclosed is a frame header detection method, comprising: receiving a data stream of frame data, and caching the received data according to the length of M bits, so that groups of bit sequences, with each group having a length of M bits, are obtained, where M is less than the length of the frame data and greater than or equal to the length of a frame header; after a group of bit sequences are received each time, performing a correlation operation on a pre-stored frame header sequence and corresponding data in a sliding window of current serial data; and detecting the frame header according to a result of the correlation operation, wherein before the frame header is detected, after a data stream with the length of one frame is received each time, the sliding window slides one bit, and after the frame header is detected, the sliding window stops sliding. In the method, a frame header is detected by comparing data received after sliding and shifting are performed with a frame header sequence to realize frame alignment, so that the caching of a great deal of data and frequent sliding searches are avoided, and related processing resources are saved.
