- A Symbol Estimation Scheme for Alamouti Coded OFDM Systems
- In Alamouti coded OFDM systems, the simple decoding at the receiver relies on the assumption that the subchannels are flat fading, decoupled, and quasi-static so that each subchannel does not change over an Alamouti codeword period two consecutive OFDM symbol periods. When the channel is fast fading, however, these assumptions...

- Influence of Power Control and Link-Level Retransmissions on Wireless TCP
- A fundamental assumption of the tcp protocol is that packet losses indicate congestion on the network. This is a problem when using tcp over wireless links, because a noisy radio transmission may erroneously indicate congestion and thereby reduce the tcp sending rate. Two partial solutions, that improve the quality of...

- Improving TCP Performance Over Mobile Wireless Environments Using Cross Layer Feedback
- Transmission Control Protocol TCP is known to suffer from performance degradation in mobile wireless environments. This is because such environments are prone to packet losses due to high bit error rates and mobility induced disconnections. TCP interprets packet losses as an indication of congestion and inappropriately invokes congestion control mechanisms,...
