摘要
According to this method, on transmission, the signal S1(t) from a low-rate digital channel is added to that S2(t) from a high-rate digital channel by over-modulation or superposition means (13) which generate a composite transmission signal S(t). On reception, the signal S2(t) from the high-rate digital channel is recovered thanks to regeneration means (24) operating on the composite transmission signal S(t). The signal S1(t) from the low-rate digital transmission channel is recovered thanks to means (25) for subtracting the composite transmission signal S(t), previously filtered by a first low-pass filter (31), and the regenerated signal S2(t) from the high-rate digital channel, previously filtered by a second low-pass filter (33). …IMAGE…
