Abstract
Systems and methods for detection of a ternary sequence are provided. An example apparatus includes a receiver configured to receive an OFDM signal comprising a plurality of OFDM Resource Elements (REs). A processor is coupled to the receiver and is configured to detect a presence of a known ternary sequence in the received OFDM signal. The processor is configured to detect the ternary sequence by determining a correlation between a first set of the OFDM REs and a first set of symbols of the ternary sequence. A power of each RE of a second set of the OFDM REs is determined. A sum of the powers is determined. A detection value is based on the correlation and the sum. The ternary sequence is determined to be present in the signal based on a comparison of the detection value to a threshold.
