1. A method for receiving downhole telemetry data from a drilling operation, the method comprising:
transmitting data from a downhole location by mud pulse telemetry;
receiving the transmitted mud pulse telemetry data at one or more transducers, each of the one or more transducers positioned at a different location of the drilling operation;
processing the received data from the one or more transducers to decode the transmitted data into a plurality of candidate decoded data items, wherein processing the received data from the one or more transducers comprises decoding the received data with a plurality of decoding chains into the plurality of candidate decoding items; and
selecting which one of the candidate decoded data items most likely corresponds to the transmitted mud pulse telemetry data, wherein selecting which one of the candidate decoded data items most likely corresponds to the transmitted mud pulse telemetry data comprises selecting an output of one of the decoding chains which is the most likely to be correct and wherein the output which is the most likely to be correct is determined by comparing confidence of the plurality of decoded data items.
