base on the shannon capacity limit,dicuss the possibility of transmitting information when siganl is lower than the noise? some ways of trasmitting would be be spreading the specturm,using reed coding method. what are some other ways to transmit information when signal is lower than the noise

I guess you are interested in "near shanon limit" transmission. You may search some papers on "LDPC" coding and also "Turbo" coding but it depends on your channel. eg. A. Near Shannon limit performancd of low density parity check codes. David JC MacKay,Cavendish Laboratory, Cambridge University B. C. Berrou, A Glavieux, and P. Thitimajshima, Near Shannon Limit Error-Correcting Coding I am not sure what you are refering to "Reed" coding - probably, you might have tried the "Reed-Solomon" coding to get expected results!
