An overlapped multiplexing-based modulation and demodulation method and device are disclosed. In the modulation method, a precoding structure is used, and a transmit end first performs parity check product code-based coding on an input information sequence, generates a factor graph for a coding result and according to a coding rule, then performs overlapped multiplexing-based modulation and coding, and transmits a coded signal by using an antenna. In the demodulation method, a signal is transmitted by using a channel, and after receiving the signal by using an antenna, a receive end first performs digital signal processing, including processes such as synchronization and equalization, then performs overlapped multiplexing-based demodulation and decoding, and finally performs factor graph-based belief propagation decoding on a decoding result, to finally obtain a decoded sequence. In this application, a product code-based decoding method is used, a parity check code is used as a subcode, and a belief propagation idea of the factor graph is applied to a decoder end. Therefore, a parity check product code in a simple structure is used. In addition, in the method, the factor graph is used in a decoding process, thereby reducing operation complexity.

A computer-implemented method of managing bookmarks within a collaborative application can include receiving a user input specifying a universal resource locator (URL) to be bookmarked and determining whether a bookmark record including the URL exists. Responsive to determining that a bookmark record including the URL does not exist, an address and a network type for the URL can be determined. A bookmark record including the URL and the network type can be stored.
