15.3 A 477mW NoC-Based Digital Baseband for MIMO 4G SDR
"... Baseband processing for advanced Telecom applications have to face two con-tradictory issues [1]. The first one is the flexibility required, with the exploding number of modes for a single protocol (e.g. 63 for 3GPP-LTE), the number of protocols to be supported by a single chip (>10 in 2010) and ..."

INTRODUCTION TO IMPULSE RADIO SYSTEMS THE TERM wideband, as applied to communication systems, can have different meanings. In conventional systems
A simple cooperative diversity method based on network path selection
- IEEE J. SELECT. AREAS COMMUN
, 2006
"... Cooperative diversity has been recently proposed as a way to form virtual antenna arrays that provide dramatic gains in slow fading wireless environments. However, most of the proposed solutions require distributed space–time coding algorithms, the careful design of which is left for future investi ..."

for cooperation between the source and the destination. We develop and analyze a distributed method to select the best relay that requires no topology information and is based on local measurements of the instantaneous channel conditions. This method also requires no explicit communication among the relays
Habitat monitoring: application driver for wireless communications technology
