A CNN-SE-BiLSTM Detection Model for Ultrasonic Wideband Signals Over Intra-Body Fading Channels
To enable safe and reliable intra-body communication (IBC) for medical applications, ultrasonic wideband (UsWB) technology employs low-duty-cycle pulses with time-hopping spread spectrum to effectively mitigate multipath and thermal effects. However, transient waveform distortion and multipath delay spread, which are i...
