A hybrid decoding method and a gigabit Ethernet receiver using the same are provided. The hybrid decoding method and the gigabit Ethernet receiver detect and determine error propagation due to burst interference in a currently used main P-tap parallel decision feedback decoder, decode an Ethernet data stream using a trellis coded modulation (TCM) decoder, and determine a follow-up main decoding algorithm according to the decoded results of the two decoders in the same time interval to effectively prevent error propagation due to burst interference.
