A means of providing radio broadcasting services by using Frequency Modulation
(FM) technique is called FM Broadcasting. Aeronautical Communication Service
refers to radio communication service intended for the safety operations of aircrafts.
Aeronautical communication service is categorized by International
Telecommunication Union (ITU) as a primary service. This service needs to be
offered under frequency interference free environment for ensuring aircrafts
navigation safety. However, different studies have shown that there exist frequency
interferences on this service which are caused by Frequency Modulation (FM) Band
Broadcasting services through frequency intermodulation products.
Performances of different Electromagnetic Interference (EMI) mitigation techniques
were analyzed by simulation method using Python, a high level multipurpose
programming language. Performance analysis of different EMI mitigation techniques
was based on Signal – to – Interference-plus – Noise Ratio(SINR) metric as a criterion.
The results show that by using reduction of transmitter power technique at the
transmit power of 40dBm,a dipole antenna and corner reflector antenna give SINR
values of 6.72 dB and 13.05 dB respectively. In reducing transmitter power to 30
dBm, the SINR values for a dipole and a corner reflector antenna were-3 dB and 2.98
dB respectively. In this technique a dipole antenna performed better as compared to
corner reflector antenna.
On the other hand, by using antenna beam tilt technique, a SINR value of 14 dB is
achieved at 0.5 degree of tilt angle and atilt angle of 1 degree gives 22 dB as SINR
value when a corner reflector antenna is used. A dipole antenna gave SINR value of
7.5 dB at 0.5 degree and 16.4 dB at 1 degree. In this technique, a dipole antenna
performed better than a corner reflector. In both techniques a dipole antenna had
better performance in EMI mitigation effect.
