“Some Strategies to Efficient Spectral Usage”

ABSTRACT

The widespread use of mobile devices with high processing capabilities, with the increasing number of users and growing demand for higher data rates, leads to unprecedented demand for data traffic over mobile communication networks.  As a result, these mobile broadband devices are spectrum-hungry requiring the search for new technologies enabling efficient spectrum usage.  There is a large number of possible solutions to improve the use of the spectrum available.  In this presentation, we describe three tools that might be considered for efficient spectrum usage.  First, we show one solution, among many, of a block transceiver with superfast implementation employing a range of values for the redundancy starting from the minimum up to the standard values.  After that, we describe a strategy to detect adaptively white spaces in the radio spectrum.  Finally, we describe how to design optimal pilot symbol patterns based on a simple post-equalization signal-to-interference noise ratio (SINR) framework, taking channel estimation errors into account.
