In terms of channel bandwidth cost, Communication cost is controlled by government's rules and regulation. But a researcher can make an effort to reduce the effective communication cost by reducing signal bandwidth. If signal bandwidth is reduced by any algorithm then more numbers of communication signals can be transmitted through same channel with rated bandwidth cost. Lager the number of communication signal transmitted bandwidth cost will be distributed over all communication signal carrier, effectively reducing the communication cost.
Signal bandwidth can be reduced either by compressing data signal or by effective channel coding reducing the number of data bit with information signal. Thus to reduce the signal bandwidth, a engineer can work either in the area of source coding or in the area of channel coding.
