Abstract: In a system for transmitting information via a time-varying transmission channel, learning information is transmitted in addition to wanted information to enable the transmission channel to be estimated at the receiving end. The system estimates if it is necessary to transmit learning information given the current variations of the transmission channel and transmits learning information only if this is deemed necessary.

Abstract: In a method for handover between old and new cells of a time-division multiple access (TDMA) cellular mobile radio system a call between a mobile station and the system, initially effected via the old cell on a first channel defined by a first on air timeslot and a first set of frequencies comprising at least one frequency, is effected via the new cell on a new channel defined by a second on air timeslot and a second set of frequencies comprising at least one frequency. The first and second on air timeslots are identical, the first and second sets of frequencies are separate, and the method consists in transmitting, after verifying that the second on air timeslot identical to the first on air timeslot is available in the new cell, a frequency indication message indicating to the mobile station the second set of frequencies so that the mobile station continues the call using the same on air timeslot and the second set of frequencies.

Abstract: A method for adjusting the length of a data block in a time-division multiple access communication system includes estimating the impulse response of a communication channel from received symbols of a reference sequence, estimating a signal-to-noise ratio from the channel impulse response, and estimating a maximum Doppler shift. Using these estimations, upper and lower limit functions of a normalized estimated mean squared error are calculated, and the length of the data block is adjusted to an optimal length determined from the upper and lower limit functions.

Abstract: A method manages the state of a plurality of micro base stations inside a mobile communication network. The network comprises at least a macro cell containing at least one Tracking Area covering a plurality of micro cells each one associated with a micro base station. The method to manage the states of micro cells comprises the steps of: switching on of all the micro base stations contained in said Tracking Area of the macro cell, counting of the messages of paging to determine the number of portable devices in Idle mode inside said Tracking Area, and switching off at least one micro base station in the Tracking Area when the number of portable devices in Idle mode in the said Tracking Area is lower than a first determined value. According to an improvement, the switching on of all the micro base stations contained in a Tracking Area is triggered when the current load of the macro cell exceeds a second determined value.

Abstract: The invention provides a green process for direct oxidation of a large number of substituted or unsubstituted cinnamaldehydes or cinnamyl alcohols into the corresponding alkyl or aryl cinnamates in one step. The process of the present invention is a convenient and efficient green process for the preparation of various aryl or alkyl cinnamates under conventional, microwave and ultrasound directly from cinnamaldehydes or cinnamyl alcohols in the presence of an oxidizing agent, catalyst and an alcohol, with or without an organic solvent. These esters are immensely important compounds in flavor, perfumery and pharmaceutical industries. There are several prior arts available for the preparation of cinnamic esters, but all of them suffer from deficiencies such as use of expensive reagents and catalysts, harsh reaction conditions, use of toxic chemicals and others. In contrast, the present methodology is extremely simple and involves reaction of the substrate with an oxidizing agent mixed with a homogeneous or heterogeneous catalyst and an alcohol with or without organic solvent by stirring at room temperature or refluxing or under microwave or ultrasound irradiation to get the requisite products.

Abstract: A security model is provided that controls access to a secured application. Under the security model, a submitting user is authenticated when the user submits a message to have the application perform an action. The application is then used to determine if the submitting user is authorized to submit messages on behalf of a source endpoint stored in the message. A method in the application is then invoked to perform the action while impersonating a source endpoint user stored in the message.
