1. A receiver device, comprising:
a receiver front end circuit that is configured to receive a signal;
a plurality of band-pass filter circuits that are configured to band-pass filter each of multiple encoding frequencies of the received signal, wherein the frequencies are in the High Frequency (HF) spectrum;
a plurality of integrator circuits that are configured to integrate particular sub-channels of a plurality of sub-channels at least until an integrated value from at least one integrator circuit of the plurality of integrator circuits crosses a detection threshold; and
a detector circuit that is configured to, in response to the integrated value from the at least one integrator circuit of the plurality of integrator circuits crossing the detection threshold, decode a message encoded in the signal from integrated values from each of the plurality of integrator circuits, wherein a meaning of the message is known a priori to the receiver device, wherein the message includes at least one of: a request for a financial transaction, a request for information regarding at least one financial instrument, information regarding at least one financial instrument, or a status indication associated with at least one financial instrument.
