Transmission Characteristics of DQPSK-OFDM for Terrestrial Digital Broadcasting Systems
Summary :
OFDM (Orthogonal Frequency Division Multiplexing) is a useful digital modulation method for terrestrial digital broadcasting systems, both for digital TV broadcasting and digital audio broadcasting. OFDM is a kind of multicarrier modulation and shows excellent performance especially in multipath environments and in mobile reception. Other advantages are its resistance to interference signals and its suitability for digital signal processing. When each carrier of the OFDM signal is modulated with DQPSK, we call it DQPSK-OFDM. DQPSK-OFDM is a basic OFDM system, which is especially suitable for mobile reception. This paper describes how a DQPSK-OFDM system works and shows several experimental and simulation results. The experimental results mainly concern the performance of the DQPSK-OFDM system relative to various disturbances such as multipath (ghost) signals, nonlinearity of the channel, and interference from analog signals. The transmission characteristics of DQPSK-OFDM are investigated and the basic criteria for the system design of DQPSK-OFDM are discussed.
