It is known that for avoiding intersymbol interference (ISI), certain time-domain constraints for designing optimal pulse shaping filters should be considered. In this paper, the Lagrange multiplier approach is applied, and the constraints are easy to incorporate into the design procedures, which makes the method attractive for designing pulse shaping filters. Comparing with the existing methods, the method is simple and effective. Numerical design examples such as Nyquist filters and partial response filters are presented to demonstrate the usefulness and flexibility of the method.","PeriodicalId":231368,"journal":{"name":"Proceedings of APCCAS'94 - 1994 Asia Pacific Conference on Circuits and Systems","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127396465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the same rationale as the CSMA/CD protocol, this protocol is designed to avoid collision or congestion of traffic before formal transmission of a packet. By the handshake procedure, the intended transmitter is able to test the channel quality and the receiver's status using a very short handshake packet. Therefore, channel traffic can be controlled to avoid overload. The throughput and reliability are analyzed based on the underlying Markovian models. Numerical results are compared to other error control schemes and show that with a reasonably short handshake time compared to the packet transmission time, this handshake protocol with simple forward error correction offers an excellent alternative for error control and can even improve the throughput performance.","PeriodicalId":231368,"journal":{"name":"Proceedings of APCCAS'94 - 1994 Asia Pacific Conference on Circuits and Systems","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124535040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
