Abstract

The invention discloses a distributed scheduling method based on successive interference cancellation in an MIMO wireless network. The method comprises the following steps of: dividing different interference regions Ali, Bli and Cli according to a maximum cumulative interference value tolerable by a link li where a receiving node ri in a network is located; controlling each link node in the interference areas Ali and Bli to broadcast weight information of respective link to a receiving node ri; and performing feasibility judgment on each link in the interference areas Ali and Bli according tothe weight information and constraint conditions, so as to obtain a feasible scheduling set, wherein the constraint conditions are conditions satisfying SINR and SIC and maximizing the minimum reachable end-to-end throughput. According to the method, the constraint conditions are set to meet the conditions of SINR, SIC and maximum minimum reachable end-to-end throughput, distributed scheduling iscarried out according to the weight information and the constraint conditions, the purpose of maximizing the minimum reachable end-to-end throughput is achieved, and the network throughput is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a distributed scheduling method based on successive interference cancellation in a MIMO wireless network. Background technique [0002] In recent years, with the in-depth research and wide application of wireless communication technology, wireless networks have developed rapidly. In addition, the rapid development of many real-time multimedia services, high-speed broadband services, inter-vehicle communication and other application fields has put forward new high-performance requirements for throughput, real-time performance, and bandwidth. The defects of existing wireless networks have become increasingly obvious, and network capacity problems Especially prominent. Wireless network Multiple-Input Multiple-Output (MIMO) technology can simultaneously transmit multiple data streams in independent parallel channels without additional bandwidth or transmission power, effec...
