Abstract: Presented herein are techniques to reduce error probability and eliminate the lingering signal that causes problems during audio signal data transmission. An electroacoustic transducer of a first electronic device receives a data encoded audio signal that includes modulated digital data therein. The data encoded audio signal is demodulated to produce a present input signal that includes a target frequency and a lingering effect of a previously received data encoded audio signal. Lingering cancellation is performed on the present input signal to produce a present output signal from which the lingering effect of the previously received data encoded audio signal has been removed.
