Abstract
In today’s communication system, satisfying users
demand is very challenging and difficult due to the increase in
multimedia and internet applications requirement within the
limited radio spectrum coupled with multipath fading and
interference. Signaling techniques that are robust and efficient
need to be investigated and developed. Diversity techniques that
used multiple antennas such as space time wireless technology
has been proposed to improve the wireless communication in a
multipath fading, interference, and signal scattering wireless
links. This paper proposed an extended Alamouti’s scheme based
on orthogonal space time block code (OSTBC). This proposed
scheme is aimed to improve the wireless system efficiency in
multipath fading links technique, also it improves the Multiple
input multiple output (MIMO) Raleigh fading channel, and
minimizes the bit error ratio (BER). The model is developed in
MATLAB environment and performance of the model is
analyzed in terms of BER vs Signal to Noise Ratio (SNR).
