Embodiment Construction
[0014] Please refer to FIG. 1 , which is a schematic diagram of a first embodiment of a decoding device 100 of the present invention. In this embodiment, the decoding device 100 is applied to a multi-tone (multi-tone) system, for example: an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) system, and the received signal R is a multi-tone signal, so the received signal R contains multiple sub-data transmitted by different sub-carriers respectively. Those familiar with communication technology should also understand that the technology described in the following embodiments of the present invention can also be used in other communication systems, whether wired or wireless, and not limited to OFDM systems. As shown in FIG. 1 , the decoding device 100 includes a channel response compensation unit 102 , a scaling unit 104 , a quantizer 106 , a soft decision decoder 110 and a scaling factor generating unit 114 . First, the channel respo...
