Communication device and digital encoding method thereof

Abstract

The present invention provides a communication device and a digital encoding method thereof. The communication device comprises a first and a second emitting devices respectively communicating at a first and a second communication channels. Each emitting device emits the same piece of data through continually emitting the same signal section for six times. The signal section is encoded in five bits. A receiving device alternately jumps between the first and second communication channels to receive signal sections emitted by the first and second emitting devices. The time of the receiving device at each communication channel comprises a phase lock time and a reception time of a whole signal section. The present invention has the advantages of having a very good quality of data transmission, reducing the cost, saving installation space, and facilitating the operation.

1 . A communication device applied to wireless peripherals of computer, said communication device comprising: 
 at least two emitting devices being a first emitting device and a second emitting device, said first and second emitting devices respectively communicating at a first communication channel and a second communication channel, each of said emitting devices continually emitting a plurality of identical signal sections in a time interval; and    a receiving device jumping at least between said first and second communication channels, the time of said receiving device among each of said communication channels comprising a phase lock time and a reception time of a whole signal section.    
   
   
       2 . The communication device as claimed in  claim 1 , wherein the number of times for which each of said emitting devices emitting the same signal section in the time interval is at least three times the number of communication channels between which said receiving device jumps.  
   
   
       3 . The communication device as claimed in  claim 1 , wherein each of said signal section is transferred by using five-bit digital codes.  
   
   
       4 . A digital encoding method of communication device, wherein each signal is transmitted by using five-bit digital codes, and there are at most two successive identical bits in each of said five-bit digital codes so that there are at most four successive identical bits in each signal of communication data.
