    Abstract: A receiver is disclosed at the head-end or a centralizing unit side in a communications system or network for signals in the upstream direction which is the direction from user to head-end or a centralizing unit that is linked to a number of users, the number being equal to or larger than one. The receiver is suited for the reception of burst mode signals. The receiver performs a channel estimation on a per-burst basis in real time or essentially immediate. The channel estimation is necessary to do successful data detection of modulated data. The receiver of the invention performs the channel estimation and data detection in one compact all-digital mechanism that has no tuning parts. The reception method works in an aspect according to the principle of a matched filter receiver, but stores no local copy of the required matched waveform. Rather, a copy of the matched waveform is included in the preamble of the signals.

    Abstract: A method and apparatus for receiving and converting spread spectrum signals is disclosed. The method and apparatus allow the receiving of spread spectrum signals and different frequency bands substantially simultaneously on the same chain of hardware components. The received signals are processed on the chain of hardware components and the resulting signal thereafter can further be used within an electronic circuit. The method includes the steps of converting analog signals into a lower frequency digital signal. The conversion step includes capturing a plurality of incoming signals within a predetermined spectral range, filtering out of the incoming signals a first plurality of analog spread spectrum signals in a plurality of analog spread spectrum signals in a plurality of predetermined bands with predetermined widths, and sampling the analog signals with a sampling frequency F.sub.s wherein F.sub.s is chosen such that the resulting time-discreet signal comprises a second plurality of analog spread spectrum signals, being the first plurality of analog spread spectrum signals which have been aliased without substantial self-aliasing.

    Abstract: The invention relates to methods and apparatus suitable for executing a service or application at a client peer or client side, having a client specific device or client specific platform, with a reconfigurable architecture, said service or application being provided from a service peer or a service side. In a first aspect of the invention, the method comprises transmitting to the client peer from the server peer an abstract bytecode. The abstract bytecode is generated at the service peer by performing a compilation of an application. The abstract bytecode includes hardware bytecode and software bytecode. At the client peer, the abstract bytecode is transformed into native bytecode for the client specific device.
