Original Abstract

Today’s most widely used broadband communication systems are based on Orthogonal Frequency Division Multiplexing (OFDM) modulation format due to its numerous advantages (e.g. resistance to multipath propagation, high spectral efficiency). However, OFDM is very sensitive to In-Phase and Quadrature (IQ) errors in the transmitter and receiver front-ends. This paper deals with the study IQ-error influence on the performance of te second generation digital video broadcasting standard (DVB-T2). Ricean and Rayleigh fading channel models with 12 echo paths are used to emulate a rooftop reception scenario. Furthermore, three low complexity methods to suppress different IQ-errors are tested and compared. Bit error rate depending on carrier-to-noise ratio is used to describe the performance of DVB-T2 system influenced by IQ-errors. Results reveal that a DVB-T2 receiver can successfully eliminate lower level of IQ-errors without compensation techniques.
