Blocking probabilities with these arrangements are derived and the dynamic sharing with bias (DSB) rule is suggested for increasing the trunking efficiency. A simple handoff model is formulated and analyzed for comparing the probabilities of additional handoffs due to sectoring and overlaying of cells. With the nominal allocation of 60 channels per cell and a donor cell having a load of 30 Erlangs, numerical results show that at blocking requirements of 1% channel borrowing with cell sectoring can increase the traffic load in the hot-spot cell from 47 Erlangs to 63 Erlangs, whereas with the use of the DSB rule the load can be increased further to 71 Erlangs. A slightly higher load can be carried in the hot-spot cell with the use of the cell overlaying arrangement. Under the technical assumptions, probability of an additional handoff for the sectorized arrangements is found to be about half of that for the cell overlaying arrangement.<<ETX>>","PeriodicalId":170618,"journal":{"name":"[Conference Record] SUPERCOMM/ICC '92 Discovering a New World of Communications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115989082","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}

Some advanced services that are derived from network capabilities and are being offered to telecommunications users are examined.

The new DD algorithm, the soft decision-directed equalization algorithm, is most effective for reconstructing binary phase shift keying and quadrature phase shift keying signals. The new DD blind equalizer can converge in closed eye situations. In the simulations, the performance of the soft DD algorithm was illustrated by applying it to a two-dimensional digital mobile communications system. A time-varying multipath fading channel model was used as the transmission medium. The performance of the soft DD blind equalization algorithm is compared to that of the standard DD algorithm, the maximum-level-error (MLE) algorithm, and the fast recursive least squares decision-feedback equalization (FRLS-DFE) algorithm. The simulation results demonstrate the improvement in performance achievable with the proposed soft DD equalization algorithm.<<ETX>>","PeriodicalId":170618,"journal":{"name":"[Conference Record] SUPERCOMM/ICC '92 Discovering a New World of Communications","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122980368","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}
