In this paper a new technique that is fun&- mentally simple and hear is described; it is effective even when the i-f filter responses to the various impulses overlap, as long as the number of overlapping responses is not great. The only important assumption made is the one that is fundamental in all impulse-noise studies - that the individual bursts have durations that are substantially shorter than the duration of the shortest important message element. This technique (which we call the linear-cancellation technique\") makes use of an important property of the impulse response of a linear filter - that its maximum value is directly proportional to the filter bandwidth. This technique is applicable to the reception of all types of modulation, even to pulsed transmissions, subject, of course, to the fundamental assumption about the duration of the input noise pulse relative to the duration of the shortest important message element.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1960-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130393479","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}

Many exchanges are now unattended and the mobile subscriber must be able to dial his calls and receive calls in the same manner as with his office or home dial telephone. The transmission of the dialing information from a moving vehicle into the exchange, with the accuracy required to meet telephone standards, has presented an interesting challenge in view of various radio propagation characteristics often experienced, particularly from weak signal or fringe areas. The pushbutton type of dialing described in this paper provides a digital signalling system employing tones of sufficient duration to ride over the numerous signal drop-outs sometimes lasting more than 100 milliseconds. Extensive field experience has proven this approach to be highly reliable and consistent in dialing from a mobile unit. A unique application of counter tubes and transistor switching circuits is employed in the conversion of the tones into dial pulses at the base station terminal. The use of pushbuttons has been found to be very convenient for mobile service. A number of the various features incorporated in mobile dial systems are described in this paper.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"3 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1960-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130013683","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}
