A Novel Self-Pilot-Based Transmit-Receive Architecture for Multipath-Impaired UWB Systems

E. Baccarelli, M. Biagi
2004 IEEE Transactions on Communications  
Aimed by these considerations, in this letter, we present a novel transmit-receive scheme allowing blind channel estimation and minimum mean-square error linear channel equalization.  ...  Essentially, the proposed scheme exploits a very short duration of the UWB pulse for achieving reliable blind deconvolution of the received signal.  ...  Proposed Self-Pilot-Based Transmit-Receive Scheme To cope with the impairing effects induced by ISI, in this letter, we propose to adopt a novel transmit scheme where the radiated UWB signal in (1) is  ...

Supercommons: Toward a Unified Theory of Wireless Communication

Kevin D. Werbach
2003 Social Science Research Network  
A universal communication privilege, allowing anyone to transmit anywhere, at any time, and in any way, should be the baseline rule for wireless communication.  ...  Regulatory proposals based on spectrum as a physical asset denominated by frequencies artificially constrain mechanisms that exploit this "supercommons," producing inefficient outcomes.  ...  A system employing inefficient receivers has less capacity than a system that swaps those out for better devices, even if the system architecture remains constant.  ...
