摘要： A method of received data assessment, the method comprising producing for each of a plurality of received data sequences a respective correlation metric, which describes the fit to the respective received sequence of the most likely of a set of candidates for the received sequence. On the basis of the correlation metrics a received sequence is determined. A validation of the determined sequence can be performed by comparing either the respective correlation metric or an associated error metric to a threshold.

摘要： A multi-path searcher comprises multiple correlators (Co, C1, C2, C3……CN) which each process a predetermined scrambling sequence and channelisation code to carry out a correlation measurement on a received pilot signal after it has been delayed by a different time delay (D) at the input of each correlator. Multiple correlation measurements (MO, M1, M2……MN) are generated and analysed (A) in relation to the time delays to identify the multi-path positions. First candidate multi-path positions are identified over a first predetermined integration period (TP1) and are stored and compared with second candidate multi-path positions derived from multiple correlation measurements made subsequently by the multi-path searcher over a second predetermined integration period (TP2) in relation to a first pilot signal. Said first and second candidate multi-path positions are confirmed or rejected to define modified multi-path positions. Said successive predetermined integration periods (TP1, TP2) are spaced apart to accommodate one or more similar sets of successive integration periods in an interleaved manner, and the same multi-path searcher is used to determine multi-path positions in relation to the pilot signal received in connection with each of different cells (CELL 1, CELL 2,……CELL S). Thus, the multi-path searcher carries out a first correlation cycle (T1) in relation to the pilot signal of each of different cells in succession to determine first candidate multi-paths for each, and then carries out a second correlation cycle (T2) in relation to each of the pilot signals again to determine second candidate multi-paths for each to modify the respective first candidate multi-paths.

MN）并与时间延迟相关地分析（A）以识别多路径位置。在第一预定积分时段（TP1）上识别第一候选多路径位置，并将其与第二预定积分时段（TP2）之后多路径搜索器随后作出的多次相关测量中导出的第二候选多路径位置进行比较和比较）相对于第一导频信号。所述第一和第二候选多路径位置被确认或拒绝以定义修改的多路径位置。所述连续的预定积分周期（TP1，TP2）以交错的方式被隔开以适应一个或多个相似的连续积分周期集合，并且相同的多路径搜索器被用于确定与导频信号有关的多路径位置与每个不同小区（小区1，小区2，......小区S）相关地接收。因此，多路径搜索器相继执行与每个不同小区的导频信号有关的第一相关周期（T1），以确定每个小区的第一候选多径，然后执行第二相关周期（T2）关于每个导频信号再次确定第二候选多路径以便每个修改相应的第一候选多路径。

摘要： Techniques are provided that can extend the efficiency of a switching regulator further into the low current region by making use of the available knowledge on predictable load variations and voltage ripple tolerance across different states, providing improved efficiency and reducing total current consumption. The load current requirement in low power states is provided using switch mode rather than linear regulation, the switch mode operation being controlled by a mode dependent control circuit so as to minimize the energy cost of the switching operation in each mode and thus obtain improved efficiency from the power source.

摘要： A Viterbi trellis processing technique in which soft decisions and hard decisions are derived from a received signal and the soft decisions are enhanced by being modified using the hard decisions. A log likelihood ratio for a bit of the received signal can be derived by grouping candidate metrics associated with the decision that the bit has a first state, grouping candidate metrics associated with the decision that the bit has a second state, applying respective functions to the groups and calculating the difference of the function values.
