Resum
We present a parallel modem for 2400 b.p.s. data transmission over high-frequency (h.f.) ionospheric channels. Time-redundancy (convolutional coding) and frequency diversity (parallel transmission with pre-encoding) are used in order to combat the frequency-selective fading and the narrow-band interference commonly shown by these channels. In-band real-time channel evaluation (RTCE) techniques are used in order suitably to select the best sub-bands from the redundant set, and to form the origina...
