    Abstract: A receiver for a multi-mode wireless device is provided. The receiver has multiple analog RF front end modules, with each module supporting a different mode of operation. The receiver has a single digital backend module for generating a digital baseband signal. A controller selects one of the available RF modules to use, and the selected RF module provides an analog communication signal to the digital backend. Each available mode has an associated set of factors. When a particular mode is selected, the set of factors associated with the selected mode is provided to the digital backend. The digital backend uses these factors to adjust the processing characteristics of its components, such as its analog to digital converter, filters, and gain controller. In this way, the single digital backend is adaptable to the requirements of each of the available radio modes.

    Abstract: The present invention relates to re-configurable signal processing modules in particular, although not exclusively, for wireless communications terminals. In general terms in one aspect the present invention provides a system for reconfiguring a signal processing module having a number of re-configurable resources such as re-configurable hardware blocks including ASIC's and field programmable logic gate arrays (FPGA's), as well as software modules for implementing different functions and which can be run on a DSP or other processing platform within the signal processing module. The module may be a mobile terminal or a base station in a wireless communications system for example. The system comprises means for generating a commands data structure comprising configuration commands for the resources, and may further comprise means for communicating this data structure to the signal processing module. The module has means for reconfiguring itself using this data structure. Typically the data structure will be a process timetable having time stamped configuration and run-time commands suitable for being dispatched to the appropriate resource.

    Abstract: The receiver for code division radio interface (CDMA - Code Division Multiple Access) works on the signal received from a mobile network terminal and converted into baseband, where the group of digital signals obtained represents the sum of all the signals and the codes relating to the users that are transmitting at that moment on the frequency band assigned to the service. The information destined for each user is extracted by correlating the group of digital signals received with the user's code. The receiver can be designed as an integrated circuit library cell and, as such, gives a high degree of flexibility that permits it to be integrated in various terminals.

    Abstract: A configurable all-digital coherent demodulator system for spread spectrum digital communications is disclosed herein. The demodulator system includes an extended and long code demodulator (ELCD) (112) coupled to a traffic channel demodulator (TCD) (114) and a parameter estimator (PE) (116). The demodulator also includes a pilot assisted correction device (PACD) (118) that is coupled to the PE (116) and the TCD (114). The ELCD (112) provides a code-demodulated signal to the TCD (114) and the PE (116). The PACD (118) corrects the phase error of the demodulated output data based on an error estimate that is fed forward from the PE (116). Accumulation operations in the ELCD (112), TCD (114), and PE (116) are all programmable. Similarly, a phase delay in the PACD (118) is also programmable to provide synchronization with the error estimate from the PE (116).
