The ability to support multiple communications channels per RF band is a fundamental process for many software defined radio platforms. These platforms typically employ a channelizer to extract channels from the received RF band for follow-on baseband processing, or to insert channels into the RF band for transmission.

Multiple Input, Multiple Output (MIMO) technology offers the potential for a significant increase in capacity and performance within a given bandwidth and power budget. However, these benefits must be weighed against the cost of the multiple RF front ends and additional processing necessary in supporting MIMO systems. The creation of a cost effective MIMO(More)
The JTRS Software Communications Architecture (SCA) provides important benefits in military satellite communications programs by allowing a reconfigurable MILSATCOM terminal to support multiple waveforms. Special treatment of the SCA is often required, however, in order to support the multiple user channel and high-bandwidth nature of advanced MILSATCOM(More)
The advancement of cognitive radio and dynamic spectrum access systems technologies is being driven by multiple different stakeholders including technology enthusiasts, research programs, industry consortia and regulatory bodies worldwide. These stakeholders are driving early standards developments; however their often disparate visions are leading to a(More)
