Architectural overview of the SPEAKeasy system

摘要

SPEAKeasy is a successful implementation of a software-definednradio (SDR) for military applications. It permits general-purposendigital hardware to communicate over a wide range of frequencies,nmodulation techniques, data encoding methods, cryptographic types, andnother communication parameters. The background of SDRs for military andncommercial needs is discussed, and the SPEAKeasy architecture is defined
