Abstract :
This work proposes a new approach on the frequency lock detection suitable for high QAM modulations which are used in many reconfigurable Software-Defined-Radio (SDR) systems. This work contains a reliable mechanism to enable a radio system working under very low signal-to-noise ratio (SNR) environments, with high coding gain scenarios such as TPC, LDPC, etc.
