  Abstract

In this letter, we present a symbol timing error estimation method for SOQPSK-TG modulation, which is one of the partial response continuous phase modulation schemes and defined in the IRIG-106 international telemetry standard. In the proposed method, we apply the constellation histogram of the preamble and convolutional neural network (CNN). The performance of the proposed method for symbol timing error estimation is demonstrated via simulation results.
