Outline of Final Research Achievements

This study improves the data transmission quality using systematic error correction coding. The detection of the inserted synchronization words is required to be robust against the transmission errors in wireless environments. The data stream is protected by error correction encoding and the codeword stream is transmitted. Assuming systematic encoding, the codeword stream consists of the data stream and the parity check stream. The detection performance of these inserted words is improved by using both the received data stream and the received parity check stream.
The security enhancement is also required in wireless environments, since wireless communications are vulnerable to eavesdropping from unauthorized terminals. The secrecy performance of the packet communication is improved by using the information sharing and the precoded multi-antenna transmission.
