Medium access control method based on broadcast preamble sampling for cognitive sensor network

The present invention relates to cognitive wireless sensor network technologies, and in particular to a medium access control method for a cognitive sensor network based on broadcast preamble sampling. A cognitive node in the cognitive sensor network adopts a periodical dormancy awakening mechanism. Firstly, a state of a primary user is judged by using a spectrum sensing technology. If the primary user is not active, a data sending node establishes a communication link by using a broadcast preamble code. Each neighbor node simultaneously considers information of hops from a gateway according to an awakening order, and independently determines to serve as a relay node for forwarding data. Furthermore, a transmission conflict between the cognitive node and the primary user may be caused due to return or missed alarm of the primary user. The present invention adopts a retransmission mechanism based on confirmation to ensure transmission reliability of data packets. The present invention is independent of a common control channel, and can realize reliable access of the cognitive sensor network for an authorized frequency band at low overhead.

A three-dimensional audio signal coding method and apparatus (1000) and an encoder (113) are provided. The method includes: After obtaining a first correlation between a current frame of a three-dimensional audio signal and a representative virtual speaker set for a previous frame (S610), the encoder (113) determines whether the first correlation satisfies a reuse condition (S620), where the first correlation is used to determine whether to reuse the representative virtual speaker set for the previous frame when the current frame is encoded; and encodes the current frame based on the representative virtual speaker set for the previous frame if the first correlation satisfies the reuse condition, to obtain a bitstream (S630, S640). A virtual speaker in the representative virtual speaker set for the previous frame is a virtual speaker used for encoding the previous frame of the three-dimensional audio signal. In this way, a process in which the encoder (113) searches for a virtual speaker again is avoided, to effectively reduce calculation complexity of searching for the virtual speaker by the encoder (113). This reduces calculation complexity of performing compression coding on the three-dimensional audio signal and calculation load of the encoder (113).
