Adaptive Loading Algorithms Evaluations for IMDD SMF System-based Optical OFDM Transceivers
Detailed investigations of the effectiveness of three widely adopted optical orthogonal frequency division multiplexing(OOFDM)adaptive loading algorithms,including power-loading(PL),bit-loading(BL),and bit-and-power loading(BPL),are undertaken,over < 100km single-mode fibre(SMF)system without incorporating inline optical amplification and chromatic dispersion(CD)compensation.It is shown that the BPL(PL)algorithm always offers the best(worst)transmission performance.The absolute transmission capacity differences between these algorithms are independent of transmission distance and launched optical power.Moreover,it is shown that in comparison with the most sophisticated BPL algorithm,the simplest PL algorithm is effective in escalating the OOFDM SMF links performance to its maximum potential.On the other hand,when employing a large number of subcarriers and a high digital-to-analogue(DAC)/analogue-to-digital(ADC)sampling rate,the sophisticated BPL algorithm has to be adopted.
