Coding: Pros and Cons
		n Channel or error-control coding is adding redundant bits to detect only or detect and correct errors. n Goal: Increase the operational range, reduce error probability or reduce power transmission requirements. n Typical gains are in the range of 4-5 dB in SNR for BER and much better FER gains. Much higher gains are now possible with relatively little cost than other methods. n Sacrifice: Bit rate and/or complexity.
