Abstract: PURPOSE: An encoding and decoding method of multi bit level data is provided to reduce a bit error in decoding failure by using a bit - symbol mapping table having a gray code or a bit - symbol mapping table. CONSTITUTION: In an encoding and decoding method of multi bit level data, a controller receives a transmission symbol from a transmitting end(S10). A controller detects a range of the error pattern based on a table including an error pattern of a transmission symbol and transmission symbol(S12). A controller encodes at least one of a plurality of multi-bit levels corresponding to the transmission symbol based on the range of the error pattern(S14). The controller detects at least one transmission candidate symbol corresponding to the receiving symbol. The controller detects at least one transmission candidate symbol corresponding to the receiving symbol based on a table including the transmission candidate symbol.
