Introduction to Digital Modulation

1EE4367 Telecom. Switching & TransmissionProf. Murat TorlakIntroduction to Digital ModulationIntroduction to Digital ModulationEE4367 Telecom. Switching & TransmissionProf. Murat TorlakIntroductionIntroduction In a Digital communication system, the source to be transmitted is discrete both in time and amplitude Digital information carrying signals must be first converted to an analog waveform prior to transmission At the receiving end, analog signals are converted back to a Digital format before presentation to the end user The conversion process at the transmitting end is known as Modulation The receiving end is known as demodulation or detection2EE4367 Telecom.

Digital Modulation Factors that influence Digital Modulation: Low BER at low received SIR performs well in multi-path and fading High spectral efficiency The performance of a modulation scheme is often measured in terms of its power efficiency and bandwidth efficiency The power efficiency is the ability of a modulation technique

Transmission over fiber is limited by the attenuation and dispersion. Multimode fibers may experience Multimode dispersion: The delayed rays cause pulse spreading Chromatic dispersion: Individual wavelengths may travel at different speeds. Dispersion creates an inherent operational limit defined as EE4367 Telecom.

3N/4 combinations have akak+1 =0 and only N/4 combinations have non zero akak+1. Because of the bipolar rule, the bit sequence 11 can only be encoded by two consecutive pulse of opposite polarities. This means the product akak+1 = -1 for the N/4 combinations. EE4367 Telecom. Switching & Transmission

Most existing methods resort to classification-based Class Activation Maps (CAMs) to play as the initial pseudo la-bels, which tend to focus on the discriminative image re-gions and lack customized characteristics for the segmenta-tion task. To alleviate this issue, we propose a novel acti-vation modulation and recalibration (AMR) scheme, which

Orthogonal Frequency Division Modulation (OFDM)

www.csie.ntu.edu.tw

Modulation - a mapping of the information on changes in the carrier phase, frequency or amplitude or combination. Multiplexing - method of sharing a bandwidth with other independent data channels. OFDM is a combination of modulation and multiplexing. Multiplexing generally refers to independent signals, those produced by different sources.
