WebJun 26, 2024 · Two samples per symbol is still convenient for common timing recovery implementations such as the Gardner TED (Isn't Gardner's algorithm and Early-Late gate the same thing?), and allows for a simple extraction of the one sample per symbol decisions. WebThe resulting transmitter communicates 4 Kbps data modulating a 128KHz carrier, with receiver sampling frequency of 2MHz. The receiver compensates for frequency and phase errors caused by various sources like clock drifts, Doppler shift and bit-time errors. The Costas loop and Early-Late Gate (ELG) Synchronizer are used for coherent data detection.
