Description: The Interleaved Frequency Division Multiple Ac-
cess (IFDMA) scheme is based on compression, repetition and
subsequent user dependent frequency shift of a modulated signal.
Multiple access is enabled by the assignment of overlapping but
mutually orthogonal subcarriers to each user. In this paper it
is shown that IFDMA can be regarded as unitary precoded
OFDMA with interleaved subcarriers. On the other hand,
IFDMA is shown to be a CDMA variant with frequency domain
orthogonal signature sequences and chip interleaving. Thus, it
combines the advantages of single and multi carrier transmission
such as low peak to average power ratio, orthogonality of the
signals of different users even for transmission over a time
dispersive channel and low complexity. Simulation results show
the good performance of coded IFDMA transmission over a
mobile radio channel for different data rates.

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: Adaptive equalization教程-Adaptive equalizers compensate for signal distortion
attributed to intersymbol interference (ISI), which is
caused by multipath within time-dispersive channels.
Typically employed in high-speed communication
systems, which do not use differential modulation
schemes or frequency division multiplexing
The equalizer is the most expensive component of a data
demodulator and can consume over 80 of the total
computations needed to demodulate a given signal [01]
