Abstract
Kvadraturno amplitudna modulacija (QAM) je digitalna modulacijska tehnika kod koje se prijenosnom signalu mijenjaju amplituda i faza ovisno o ulaznom digitalnom signalu. Ortogonalna modulacijska tehnika u frekvencijskoj domeni (OFDM) je tehnika kojom se raspoloživa širina prijenosnog pojasa dijeli među ortogonalnim prijenosnim signalima kako bi se postigla bolja efikasnost slanja podataka. Za brzu Fourierovu transformaciju koja se koristi u demodulatoru OFDM korištena je već postojeća IP jezgra koja je na procesor povezana preko sučelja Xillybus. Programski dio demodulatora podijeljen je na dvije dretve. Prva dretva učitava uzorke, detektira početak simbola OFDM te šalje simbole OFDM do IP jezgre za izračun Fourierove transformacije. Druga dretva čita simbole iz IP jezgre za izračun Fourierove transformacije, radi estimaciju kanala i korekciju signala te na kraju 4-QAM demodulaciju. Iz prikazanih rezultata se može vidjeti da demodulator OFDM može uspješno demodulirati signal i dobiti poslane podatke unatoč smetnjama.
Abstract (english)
Quadrature Amplitude Modulation (QAM) is a digital modulation technique where the transmission signal changes amplitude and phase depending on the input digital signal. Orthogonal frequency-division multiplexing (OFDM) is a technique by which the available transmission bandwidth is shared by orthogonal transmitting signals to achieve better data transmission efficiency. For the fast Fourier transform that is used in the OFDM demodulator, an existing IP core is used that is connected to the processor via the Xillybus interface. The program part of the demodulator is divided into two threads. The first thread loads the samples, detects the beginning of the OFDM symbol and sends the OFDM symbols to the FFT core. The second thread loads symbols that come from the FFT core, does channel estimation and equalization and at the end 4-QAM demodulation. From the displayed results it can be seen that the OFDM demodulator can successfully demodulate the signal and receive the submitted data despite the interference.
