Abstract:
The steadily decreasing cost of wireless
communications and its growing development
have resulted in its increased popularity. But the
drawback here is to limited bandwidth of
transmission medium and multipath interference.
So an important challenge in wireless system
design is the selection of an appropriate multiple-
access scheme. Among many multiple access
strategies developed so fa ,CDMA (Code Division
Multiple Access) based on IS 95 plays an
important role. CDMA encoding and decoding is
the main feature of CDMA system and it also
takes a significant amount of time because of
spreading the original signal. So an efficient
hardware is necessary for encoding and decoding
.This paper includes the CDMA encoding and
decoding technique and its real time
implementation by TMS320C50 DSP KI .
