Algorithm Design of Maritime Wireless Communication Resources Based on Interference Alignment

With the increasing tension of wireless spectrum, interference has become a bottleneck problem in future wireless communication, and the urgency of interference management is particularly prominent. Traditional interference management methods have the defects of low spectral efficiency or limited interference. As a technology that can effectively improve network freedom and spectral efficiency, interference alignment can obtain greater gain compared with traditional methods, and has great potential in theory. As an effective means of interference management, interference alignment technology has been widely studied, and the difficulty of interference alignment is how to design the precoding matrix at the transmitting end and the decoding matrix at the receiving end, so as to meet the needs of system freedom. In the field of modern maritime communication, there are more and more application fields based on wireless technology, such as maritime detection, target detection and scheduling, which need to use wireless resources for data transmission, while maritime wireless resources are very tight. This paper makes a reasonable allocation of limited wireless resources to ensure the quality of various services of maritime wireless communication. The existing wireless resource algorithms generally have high complexity, and there is still a certain space between the final calculation result and the optimal solution.
