OFDM modulationframe synchronizationsynchronization errorsThis article focuses on frame synchronization for orthogonal frequency division multiplexing modulation. At the beginning of the article general principles of this modulation are explained. Then influence of inaccurate synchronization in receiver is described...
This lecture further explores multi-carrier modulation and demodulation. Coherent demodulation of the L-th sub-carrier on an N sub-carrier system is developed from first principles. Schematic of a multi-carrier modulator and demodulator is explained. We further see how a multi-carrier system with ...
