DIGITAL RECEIVER FOR SOFTWARE-DEFINED RADIO IMPLEMENTATION

摘要

PROBLEM TO BE SOLVED: To provide a scalable digital receiver structure with a good energy efficiency that enables recognition of a spectrum environment in response to incoming wireless transmission and gradual system recovery (wake-up).SOLUTION: A digital receiver comprises: means 90 for receiving packet data; a first processing module 10 for packet detection comprising a first programmable processor 15; a second processing module 50 for demodulation and packet decoding comprising a second programmable processor 55; and a first digital receive controller 30 comprising a third processor configured to be notified of detection of data by the first processing module 10 and activate the second processing module 50.
