Abstract
 X is a discrete memoryless binary source , Sequence X undergoes
lossless transformation to satisfy the requirement â\euroœEach 1 is
separated by one or more zeros“, ”Each 0 is separated by one or two
1s” or similar condition , These conditions are the decision conditions
for error detection in channel transmission. A new channel coding method
is proposed based on a weighted probability model for lossless coding ,
The encoding rate and encoding and decoding steps of different
conversion methods are different , It is proved that the decoding error
probability can reach 0 when the code length is long enough. In the
simulation experiment of BPSK signal in AWGN channel, At 0.5 bit rate,
the proposed method improves 1.1dB over Polar code when FER is 0.001,
and 1.4dB over Polar code when FER is 0.0001.Â
