摘要： In order to minimize the energy consumption in a duty-cycled asynchronous wireless communication network appropriate values of the operation parameters, i.e. the duration of the awake interval and the duration of the sleep interval, of the routing nodes (R1, R2, R3, R4, R5, R6, R7) of the network are determined and set. The energy consumption model takes into account the effect of random access; in order to simplify the model, the network is partitioned into a plurality of clusters (CL1, CL2,...) so that each of said clusters (CL1, CL2,...) comprises one cluster-head node (R3, R4,...). According to this model, the energy consumption of a cluster is a function primarily of the probability of busy channel when the nodes of the cluster attempt transmission, the probability of communication collision during transmission, the duration of the awake interval and the duration of the sleep interval of its cluster-head node. Minimization of the energy consumption is carried out under predetermined values of the probability of busy channel and of the probability of communication collision and under predetermined constraint for the probability of successful transfer of data packets within the cluster and for the average delay of transfer of data packets within the cluster; in this way, optimal values of the duration of the awake interval and the duration of the sleep interval of the cluster-head node are determined.

摘要： A system for processing an RF signal received via a plurality of antenna elements includes a connection arrangement (6) for selecting a sub-set of a given number of RF signals ( r i , r j ) received from the antenna elements as well as a processing arrangement (8) for combining the received RF signals of the selected subset ( r i , r j ) into a single RF signal for demodulation. The system includes a RF phasing circuit (18) for producing selective combinations of the received RF signals ( r i , r j ) by applying relative RF phase shift weights to the RF signals ( r i , r j ) that are combined; each combination includes RF signals received from a number of adjacent antenna elements equal to the number of the RF signals in the sub-set to be selected. A radio performance estimator (14) generates for each said selective combination of RF signals at least one non-RF radio performance indicator (RPI) representative of the quality of the RF signals in the combination. A decision block (16) identifies the sub-set of received RF signals ( r i , r j ) to be selected as a function of the one radio performance indicator (RPI) generated for the selective combinations of said received RF signals ( r i , r j ). This arrangement facilitates the selection of the signals/antennas to be used for reception e.g. in a WLAN device by avoiding that the selection process may involve all the possible combinations.

摘要： A random number generator (100) uses the output of a true random generator (101) to alter the behaviour of a pseudorandom number generator (102). The alteration is performed by a mixing logic (103) that builds a random seed for the pseudo-random number generator (102) and comprises a generator of an alteration signal (TC1) the generation of which exploits the random instant of arrival of the bits outgoing from the true random generator (101). The alteration signal is obtained by processing the seed by means of the pseudo-random sequence.
