Multi-Carrier and Spread Spectrum Systems (PDF)

The technological progress in multi-carrier (MC) modulation led
orthogonal frequency division multiplexing (OFDM) to become an
important part of beyond 3G cellular mobile communication
standards, including LTE and WiMAX. In addition, the flexibility
offered by the spread spectrum (SS) and time division multiplexing
(TDM) techniques motivated many researchers to investigate several
MC combined multiple access schemes, such as MC-CDMA, OFDMA and
MC-TDMA. These schemes benefit from the advantages of each
sub-system and offer high flexibility, high spectral efficiency,
simple detection strategies and narrow-band interference rejection
capability.

Multi-Carrier and Spread Spectrum Systems is one of the
first books to describe and analyze the basic concepts of
multi-carrier OFDM transmission and its combination with spread
spectrum (MC-CDMA). The different architectures and detection
strategies as well as baseband-related transceiver components are
explained. This includes topics like FEC channel coding and
decoding, modulation and demodulation (IFFT/FFT), digital
I/Q-generation, time and frequency synchronisation, channel
estimation, frequency domain equalization and RF aspects such as
phase noise and non-linearity issues. Concrete examples of its
applications for cellular mobile communication systems (B3G/4G) are
given. Further derivatives of MC-SS (such as OFDMA, SS-MC-MA and
DFT-spread OFDM) and their corresponding applications in the LTE,
WiMAX, WLAN and DVB-RCT standards are detailed. Capacity and
flexibility enhancements of multi-carrier OFDM systems by different
MIMO diversity techniques such as space time/frequency coding (STC,
SFC) and software defined radio concepts are also described.

Written in a highly accessible manner this book provides a
unique reference on the topics of multi-carrier and spread spectrum
communications, assisting 4G engineers with their
implementation.
