面向智慧海洋的MIMO探测通信一体化波束成形设计
Beamforming Design of MIMO Integrated Detection and Communication for Smart Ocean
摘要
Abstract
With the continuous development of smart ocean,reliable acquisition,high-speed transmission and efficient processing of ocean information are becoming more and more important in ocean research.Therefore,we consider a MIMO integrated detection and communication system for smart ocean,which shares the same spectrum resources on the same platform to simultaneously realize underwater target detection and communication.Firstly,we investigate two integrated waveform composition methods:communication signals and the superposition of communication and probing signals.We minimize the MIMO beampattern matching error and cross-correlation of transmit beampattern under the constraints of the total power and communication user's signal to interference plus noise ratio requirements.Then,the two established beamforming design problems are transformed into quadratic semidefinite programming problems and are solved by semidefinite relaxation algorithm to obtain the beamforming matrix of integrated detection and communication.Finally,simulation results verify the feasibility of the beamforming design for MIMO integrated detection and communication.关键词
