Using Multi-Sampling Method to Recover Binary Signals

Heejong Suh~1 Zhou Xiaozheng~(1,2) Zhang Ke~2(1 Department of Electronics Communication Engineering,Yosu National University,Yosu 550-749,Korea;2 Department of Automation,Beijing Institute ofPetro-chemical Technology,Beijing 102617)  
In this paper,we propose a new method for recovering binary code sequences from base-band,FSK or PSK signals transmitted through Gaussian noise channel.Differing from the traditional method,the new method adopts multi-sampling in every code width.When sampling,if the value of the signal at the sampling point is greater than the threshold,then we denote it as '1', otherwise we denote it as '0'.According to the number of '1' within every code width,we can decide whether this code is '1' or '0'.Theoretical analysis and lots of simulation show that this method is easy to be used and is highly efficient.Using this new method,we can know the probability of bit error for every code,so this method can be combined with other channel coding methods.It has great potential to be further developed.
