Abstract :
This paper proposes adaptive digital receiver architecture suitable for software defined radio systems. This receiver is prepared to handle modulation schemes whose symbols belong to a linear, two-dimensional signal space (such as M-PSK or M-QAM). It is capable of identifying key signal parameters (e.g., symbol rate and constellation) and in an autonomous way, modifies its operation accordingly. Four aspects of self-reconfigurable are addressed: baseband filtering, symbol synchronization, carrier synchronization and constellation recognition. The performance of the receiver is evaluated based on simulation results, and several usage scenarios for the proposed architecture are envisaged.
