Processing threshold in an IEEE 802.11a/g/p receiver over GNU radio: A fuzzy logic application
Cristián Rodríguez, G. Puerto, Carlos Arturo Suárez Fajardo · 2017
This paper presents the design and implementation of a fuzzy inference system for automatic real-time environment, setting of the processing threshold in a software defined IEEE802.11a/g/p receiver. The fuzzy system behavior is established by determining the if-then rules among the membership functions, which are optimized by a differential evolutionary algorithm, for the inputs that are composed by a set of wireless network characteristic parameters and the output, threshold. The full model consists of fuzzifier, defuzzifier and inference system. The proposed development is analyzed and implemented over GNU Radio including the IEEE 802.11/a/g/p flowgraph. A proof-of-concept over USRP B210 is carried out in order to validate the design.
