    Horn Antenna Design 2.45GHz Frequency 6 дней(-я) left

    I'm looking to design a horn antenna for 2.45GHz frequency. The antenna has to follow the below specifications: - Antenna gain is to allow it to reach a maximum distance/range of 7 kilometers. - High return loss is a must. - Antenna has to be as small as possible (Physically). - At Phi=180 angular width is to be 130 degrees or more. - At Phi=90 angular width is to be 30 degrees of less. - Radiation pattern is to have a wide angle from front and back, and narrow angle from side (As described above). You are required to submit all related documents including but not limited to: - Complete antenna model (CST file). - Parameter list. - Simulations of all types (Farfield, power flow, E-field, H-field,...etc). - 3D radiation pattern (Farfield; linear and non-linear). - Polar plots. ...

    Machine Learning Spectrum Sensing in Cognitive Radio 6 дней(-я) left

    Simulation based project to investigate machine learning techniques for spectrum sensing in Cognitive radio networks with moderate complexity and best performance metric. The idea is to allow more license users to use the spectrum for a certain amount of time for optimum spectrum usage because 80% of the time the spectrum is not used effectively,most of it remains the sensing will allow for unlicensed users to utilize the radio frequency spectrum for sensing will eliminate spectrum overcrowding which causes interference. The secondary users and primary users are not allowed to secondary users must sense the spectrum to check idle spaces in the spectrum to they can use it until the primary/licensed user occupies the same space and they have to vacate the spectrum to give priority to ...
