Simulation characteristic of MIMO-OFDM using Matlab
Abstract
Multiple-antenna systems, also known as MIMO radio, can improve the capacity
and reliability of radio communication. MIMO using OFDM modulation technique related
to 802.11n is a new multi-streaming modulation technique that has recently been
developed. When apply MIMO along with OFDM, they simply exploit the spatial
dimension by increasing the number of unique spatial paths between the transmitter and
receiver and modulated broadband channel into many parallel sub-channels. The approach
taken for this project is to study and investigate the characteristic of MIMO-OFDM in term
of BER performance, channel capacity and channel estimation for both sides, transmit and
receive antenna. This project was done by simulation for MIMO-OFDM characteristic. In
this thesis, we compare two type of channel estimation, Pilot Base and Data Aided. For
BER performance, the selection on modulation type and coding rate play a significant role
for throughput of the system. This will include Alamouti code and compare it base on SNR
value to check its BER performance. Channel capacity also been simulated for various
channel of transmit and receive antenna. Then relate channel capacity when channel was
parallel after SVD technique and distributed as waterfilling algorithm. The performance for
MIMO-OFDM system will be considered channel condition and multipath effect in scatter
background.
