There is described the use of Digital Radio Frequency Memory (DRFM) modules to jam certain communication signals while allowing others to be received on a given frequency band. The DRFM modules exploit the multi-path phenomenon by using transmitted signals to cause full band destructive echoes and/or distortions. A set of receivers used in conjunction with the DRFM modules are aware of the exact multi-path induced by the DRFM modules and are therefore able to mitigate or even benefit from the effects of the destructive multi-path and maintain or improve communications.

A system and method for optimization of media objects for delivery to one of a plurality of mobile communication devices of different types and rendering thereon. In particular, the media objects are optimized according to the mobile device's characteristics to ensure efficient delivery and optimal rendering thereon. For this purpose, an optimized output of the media object is determined at a first stage. At a subsequent stage, based on the mobile device type, the characteristics of the object to be delivered are then adjusted to conform to those of the predetermined optimized output, thus ensuring that the rendering of the optimized media object on the mobile device output is of high quality.

The present invention provides for a method that could be advantageously implemented in a satellite local area network (LAN) in which an average number of sites share a TDMA link. The invention provides for both a dedicated bandwidth to all the sites and a shared bandwidth that is dynamically assigned to the sites, therefore allowing for both synchronous traffic and for on request burst mode traffic. The method includes a reservation method of this shared bandwidth which is specially optimized for a satellite link. The method provides also for a network that automatically managed its communication bandwidth resources and the synchronization of the sites, without the need of an external controller. The present invention also provides for a satellite modem to transmit data from a site, to receive data from the sites and to manage the bandwidth resources of the TDMA satellite in accordance with the above method.

A method and apparatus is disclosed for testing a reconfigurable logic block. Preferably, this invention is intended to be used with Field Programmable Gate Array. According to the invention, a test bus addressing unit and a test bus activation unit are used to perform a test on a logic block. Upon selection of a corresponding logic block, a test data is outputted on a test bus which enables a testing of the logic function.

A digital parallelized Infinite Impulse Response (IIR) integrator filter comprising a first channel having a first input and second channel having a second input, a first adder to add the two channel inputs, an integrator to integrate the added channel inputs to provide a first channel output is described herein. The second input channel is adjacent in time to the first channel input. The second channel further comprises a second adder which adds the first output with the second channel input in order to produce a second output, adjacent in time with the first output. This configuration can be generalized to n inputs and m outputs.
