<p> Space-Time Code (STC) has caused wide public concern in the field of wireless communications over the recent years. Due to interference or signal attenuation, it may cause errors or data loss when the data stream is transmitted through a wireless channel. The Space-Time Block Code (STBC), which combines the technique of channel coding and antenna diversity, is an effective approach of increasing the capacity of a wireless channel by increasing both the coding gain and diversity gain. Using STBC in Orthogonal Frequency-Division Multiplexing (OFDM), multiple antennas transmit multiple copies of the data stream, and the receiver can integrate these copies for optimal data. In this system, the wireless signal is more reliable and able to meet more remote wireless transmissions. In this project, three STBCs are applied in 2x1, 3x1, and 4x1 OFDM system respectively, to provide different data rates and reliability. </p>
