چکیده

A key issue of future wireless communication systems is that they have to be adaptive. In the Adaptive Wireless Networking (AWGN) project we aim at the implementation of adaptive wireless communication systems in a heterogeneous reconfigurable System-on-a-Chip (HRSoC). We introduce our methodologies for analyzing and mapping DSP functionality in dynamically reconfigurable heterogeneous hardware. A possible implementation of a multi-mode communication system in the MONTIUM architecture is discussed. Suggestions for future activities in the Adaptive Wireless Networking project are also given. Keywords— Reconfigurable heterogeneous hardware, Wireless communication algorithms, Software defined radio, SoC, MONTIUM

Flexible Analog Front Ends of Reconfigurable Radios Based on Sampling and Reconstruction with Internal Filtering

Bandpass sampling, reconstruction, and antialiasing filtering in analog front ends potentially provide the best performance of software defined radios. However, conventional techniques used for these procedures limit reconfigurability and adaptivity of the radios, complicate integrated circuit implementation, and preclude achieving potential performance. Novel sampling and reconstruction techni...

Enhanced MDIR receiver for space-time dispersive channels

A particular property of the matched desired impulse response receiver is introduced in this paper, namely, the fact that full exploitation of the diversity is obtained with multiple beamformers when the channel is spatially and timely dispersive. This particularity makes the receiver specially suitable for mobile and underwater communications. The new structure provides better performance than...
