摘要: A method includes storing in a mobile communication terminal a definition of a set of frequency bands in which the terminal is capable of communicating, including at least first and second frequency bands. One or more combinations of at least portions of the frequency bands in the set, which cannot be allocated in proximity to one another due to interference, are determined in the terminal. A search is conducted in the terminal over the set of the frequency bands. Upon detecting a presence of a candidate wireless network in a first portion of the first frequency band, which cannot be allocated in proximity to at least a second portion of the second frequency band in accordance with the specification, at least the second portion is omitted from the search.

摘要: A method includes assigning a communication channel for simultaneous transmission to at least first and second mobile communication terminals using a Time-Division Multiplexing (TDM) communication protocol. Upon determining that data is to be transmitted over the communication channel to both the first and the second mobile communication terminals, the data is transmitted at a first power level that is defined for transmission to the first mobile communication terminal as part of the simultaneous transmission. Upon determining that the data is to be transmitted over the communication channel only to the first mobile communication terminal, the data is transmitted at a second power level that is defined for transmission only to the first mobile communication terminal and is lower than the first power level.

摘要: A searcher for a mobile station of a cellular telephony network. Pilot signal from nearby base stations are correlated with a pseudonoise sequence inside a search window, using a bank of correlators. Each correlator is assigned a different delay, from among a sequence of delays in the window. At each delay, correlation is performed initially for a first dwell time. If the resulting correlation value exceeds a threshold, the correlation is continued for a second dwell time. Otherwise, the correlator is set to the next delay in the sequence. Only the outputs of second dwell correlations are used to identify the nearest base station. Some correlators may perform first dwell correlations at new delays in the window at the same time that other correlators are still performing second dwell correlations at old delays in the window.

摘要: A pilot acquisition unit for code division multiple access (CDMA) communication systems is provided which includes a fast Hadamard transform (FHT) unit and a pre-Hadamard processing unit. The FHT unit determines the quality, in accordance with a metric, of each of a set of possible pseudo-random number (PN) loadings and the pre-Hadamard processing unit generates a vector u per set of PN loadings. The vector u defines a quality metric of a received pilot signal with the set of possible PN loadings, the pre-Hadamard processing unit providing the vector u to the FHT unit.

摘要: A method in a receiver includes receiving from a transmitter an instruction to check for messages from the transmitter at intervals having a specified time period. A frequency error of the receiver relative to the transmitter is estimated at the receiver, and an actual time period that does not exceed the specified time period is selected based on the estimated frequency error. The receiver is activated periodically according to the selected actual time period so as to reset the frequency error.

摘要: A method used in a receiver includes measuring first Received Signal Strength Indications (RSSIs) in respective first communication channels, which are located in a given frequency band and which each have a first channel bandwidth. Based on the first RSSIs, second RSSIs are computed for respective second communication channels, which are located in the given frequency band and which each have a second channel bandwidth that is larger than the first channel bandwidth. At least one of the first and second communication channels over which to receive signals at the receiver are selected using the first and second RSSIs.
