Method for encoding and decoding a sequence of bits for transmission through the transmission channel, transmission and reception apparatus for encoding and decoding a sequence of bits.And, a system for wireless communication.Method and apparatus for encoding a sequ00b3u00eancia bits for transmission as symbols.Some of the positions of bit of symbols with a bit error rate higher than the other bit positions.The method includes the steps of: providing (31, 32, 41, 42), a plurality of sequ00b3u00eancias bits using an encoder convolucional (31, 41), in response to a sequ00b3u00eancia bits of the entry.Each sequ00b3u00eancia bits being defined by a predetermined generator polynomial having a predetermined level of sensitivity mapping; map (33.(44) the bits of each sequ00b3u00eancia bits to symbol positions based on the degree of sensitivity of the polynomial generator that defines the sequ00b3u00eancia bits.With the interleaving, the mapping of the bits of each sequ00b3u00eancia bit positions of a symbol (33, 44) can precede the step of interleaving (34) of the symbol.Or you can follow the step of interleaving (43) of the bit.
