Abstract:
1. A method of determining transmission power in a communication system, the method comprising: comparing a first modulation/Forward Error Correction (FEC) rate level, which is a modulation/FEC rate level used in a previously transmitted signal, with a second modulation/FEC rate level, which is a modulation/FEC rate level to be used in a currently transmitted signal; if the second modulation/FEC rate level is higher than the first modulation/FEC rate level, determining a transmission power using a normalized Carrier to Noise ratio (C/N) corresponding to the second modulation/FEC rate level on an ascending normalized C/N table; and if the second modulation/FEC rate level is lower than the first modulation/FEC rate level, determining the transmission power using a normalized C/N corresponding to the second modulation/FEC rate level on a descending normalized C/N table.
