I'd use a UART at the transmitting end (FIFO if you have bursts of data) -
parallel in, formats the data into a serial stream, output serial stream
(+5/0V) can modulate a carrier and be transmitted, demod at other end to
recover the formatted serial stream from the received carrier, and straight
into another UART to recover as 8 parallel bits.

Most UARTS should handle the upper limit of digital speed that a modulated
signal could cope with.
