Claim 11:
12. A system comprising:
a combiner device structured and arranged to generate a combined signal by combining (1) a first electrical signal generated by a first photodetector in response to the first photodetector receiving a multi-return light signal; and (2) a second electrical signal generated by a second photodetector in response to the second photodetector receiving the multi-return light signal, wherein the multi-return light signal comprises two or more light pulses;
a current amplifier, configured to amplify the second electrical signal generated by the second photodetector and coupled to the combiner device; and
a receiver device configured to detect the two or more light pulses by decoding the combined signal.
