Abstract: The cellular communications system includes CDMA and diversity combining with control handoff. The system has a number of mobile switching stations (MSC) connected to each other and the PSTN. These stations are connected via base stations (BS) to a mobile station (MS). An MS (30) is normally linked to the PSTN via a BS (24) an MSC (14). When the MS detects a valid pilot signal from another BS (22) it signals its MSC which establishes a diversity link (82,72,50) via another MSC (12). When the signal becomes too weak the first base station relinquishes control.

Abstract: An apparatus for translating a series of source words in a first language to a series of target words in a second language. For an input series of source words, at least two target hypotheses, each comprising a series of target words, are generated. Each target word has a context comprising at least one other word in the target hypothesis. For each target hypothesis, a language model match score comprises an estimate of the probability of occurrence of the series of words in the target hypothesis. At least one alignment connecting each source word with at least one target word in the target hypothesis is identified. For each source word and each target hypothesis, a word match score comprises an estimate of the conditional probability of occurrence of the source word, given the target word in the target hypothesis which is connected to the source word and given the context in the target hypothesis of the target word which is connected to the source word. For each target hypothesis, a translation match score comprises a combination of the word match scores for the target hypothesis and the source words in the input series of source words. A target hypothesis match score comprises a combination of the language model match score for the target hypothesis and the translation match score for the target hypothesis. The target hypothesis having the best target hypothesis match score is output. <IMAGE>
