Description: orthogonal variable spreading factor (OVSF) is an implementation of Code division multiple access (CDMA) where before each signal is transmitted, the spectrum is spread through the use of a user s code. User s codes are carefully chosen to be mutually orthogonal to each other.
These codes are derived from an OVSF code tree, and each user is given a different, unique code. An OVSF code tree is a complete binary tree that reflects the construction of Hadamard matrices.

Description: This paper analyzes the
performance of an orthogonal frequencydivision
multiple access (OFDMA) scheme in
which the carriers assigned to a user are
uniformly spaced across the channel
bandwidth and code-division multiplexing is
used between them. Zero forcing and
minimum mean-square error equalization and
maximum-likelihood detection are used to
compensate for multipath fading. It is found
that code-division multiplexing recovers most
of the frequency diversity loss inherent to
OFDMA. The analyzed scheme makes it possible
to benefit from the advantages of OFDMA
and approach the performance of MC-CDMA.

Description: THEORY OF
CODE DIVISION
MULTIPLE ACCESS
COMMUNICATION
The objective of this book is to provide an introduction to code division multipleaccess
(CDMA) communications. Our motivation for emphasizing CDMA communication
is a result of the technological developments that have occurred during
the past decade. We are currently witnessing an explosive growth in wireless
communication and cellular mobile radio systems, which are based on different
multiple-access techniques. We anticipate that, in the near future, we will see
a replacement of the current time- and frequency division methods in wireless
communication and mobile radio by CDMA.
