Analysis method of millimeter wave CF-RAN ISAC system architecture based on NA-FD

Abstract

The invention discloses an analysis method for a millimeter wave CF-RAN ISAC system architecture based on NA-FD, and the method comprises the following steps: constructing an uplink communication channel model, a downlink communication channel model and an uplink sensing channel model between user equipment and an edge distributed unit, constructing an interference channel model between uplink and downlink user equipment and an interference channel model between access points; constructing a downlink transmission model and an uplink communication model according to the channel statistical information; a progressive closed expression of downlink traversal and rate is deduced according to a downlink transmission model, a progressive closed expression of uplink traversal and rate is deduced according to an uplink communication model, and the influence of a sensing signal on the system communication performance is considered; according to the accuracy of uplink and downlink traversal and rate asymptotic closed expressions of a numerical simulation verification system, the influence of different system parameters and interference of different degrees on performance is analyzed, and the influence is compared with TDD and CCFD duplex modes. According to the invention, the performance requirements of a next-generation wireless network on diversified scenes and services can be met.
