Description: Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. High Peak-to-Average Power Ratio (PAPR), which leads to power inefficiency in the RF portion of the transmitter, is a major drawback of OFDM. Platform: |

Description: The book can be used as a basis for one course, or a two course sequence, in digital communication. The following topics are covered: complex baseband representation of signals and noise (and its relation to modern transceiver
implementation) modulation (emphasizing linear modulation) demodulation
(starting from detection theory basics) communication over dispersive chan-
nels, including equalization and multicarrier modulation computation of performance benchmarks using information theory basics of modern coding strategies (including convolutional codes and turbo-like codes) and introduction to wireless communication. -The book can be used as a basis for one course, or a two course sequence, in digital communication.

Description: Multicarrier modulation helps to reduce the detrimental effects of multipath fading. Because of its
robustness to multipath, and the ease of implementating it in transmitters and receivers using the
fast Fourier transform (FFT), the MCM concept is growing rapidly in practical importance. It can
be found today in IEEE standards 802.11a, 802.15.3 and 802.16a, as well as standards for digital
broadcasting of television and radio. This document serves to derive the multicarrier modulation
method from first principles. Platform: |

Description: 多载波调制(Multicarrier Modulation)采用了多个载波信号。它把数据流分解为若干个子数据流，从而使子数据流具有低得多的传输比特速率，利用这些数据分别去调制若干个载波。所以，在多载波调制信道中，数据传输速率相对较低，码元周期加长，只要时延扩展与码元周期相比小于一定的比值，就不会造成码间干扰。因而多载波调制对于信道的时间弥散性不敏感。多载波调制可以通过多种技术途径来实现，如多音实现(Multitone Realization)、正交多载波调制(OFDM)、MC-CDMA和编码MCM(Coded MCM)。其中，OFDM可以抵抗多径干扰，是当前研究的一个热点。-Multi carrier modulation (Multicarrier Modulation) uses multiple carrier signal. It decomposes a data stream into a plurality of sub data stream, so that the sub data stream transmission bit rate is much lower, respectively to a plurality of carrier modulation using these data.
