Suppression of interference for frequency-hopped multiple-access (FHMA) systems

Like any resources, bandwidth is a limited commodity. To maximize usage effectively, Frequency-Hopped Multiple-Access (FH-MA) system has commonly been employed in both military and commercial applications. However due to multiple-access interference (MAI) and various fading channels, the system bit-error rate (BER) performance of a FHMA system will be degraded. In this project, Matlab simulations are performed and analyzed for FH-MA and various fading channels. The modulation scheme applied throughout the project is Binary Frequency Shift Keying (BFSK). The performance results are to be generated in the end. Factors affecting the performance including number of users, types of fading channel, signal to noise ratio (SNR) are discussed. To further mitigate the degrading performance, Maximum Likelihood (ML) receiver and Linear Combining (LC) receiver are studied.Bachelor of Engineering (Electrical and Electronic Engineering
