Abstract

The invention discloses a green n cognition wireless system resource distribution method of an OFDM signal. The method is that the variational principle is utilized to perform the optimal analysis for the ratio of the transmission power to the transmission rate, so that the EPG failure index can be reduced; the pilot frequency density and the distributed energy can be optimally balanced, so as to effectively distribute the system resource by an energy saving manner.

Description

technical field

[0001] The invention relates to resource allocation of a cognitive wireless system, in particular to a resource allocation method of a green cognitive wireless system of OFDM signals. Background technique

[0002] In the historical process of promoting the "green world", green communication has inevitably become one of the main contributors. The concept of green communication requires reducing communication power consumption and improving transmission efficiency. In mobile communication systems based on OFDM technology, although the transmitted pilot signal is of great significance to channel estimation, it does not carry information, which can be regarded as a waste of system power resources to a certain extent. Therefore, a proper balance between the system performance requirements and the energy efficiency of data transmission is in line with the requirements of green mobile communication, and cognitive radio technology can be the way to realize it. In c...
