Abstract

Digital Audio Broadcasting (DAB) is an audio broadcasting technology which is becoming more important nowadays. This system will replace existing analogue audio broadcasting systems which are Amplitude Modulation (AM) and Frequency Modulation (FM) system while offering few advantages compared to the current system nowadays. The objectives of this project is to design a transmitter of Digital Audio Broadcasting (DAB) system where Differential Quadrature Phase Shift Keying (DQPSK) modulation technique will be implemented along with Orthogonal Frequency Division Multiplexer (OFDM) to overcome Intersymbol Interference (lSI) that always occur in digital audio transmission. This transmitter system will be designed and simulated using Matlab software. This transmitter will be simulated with the receiver system to ensure that it will operate in accordance to the project requirement. The results also will be compared to the analogue system to highlight the advantages ofthis system.
