Question

The data source produces a sequence selected from among four symbols at a rate of 103 symbols/s according to the following probabilities. Communication engineers want to send the data as far as possible over a wireless channel having a band width of I kHz. What bit rate is required to accurately represent the data? What error-correcting code could be used that corrects all single-bit errors? At a distance of 1 km from a transmitter, the channel's capacity is measured to be 4 kbps. How far assay can a receiver be located from the transmitter so that the data can be received without error?
