“…By making use of the signal bit rate calculation formula reported in [10], the SIPM-OOFDM-DSPM signal bit rate can be easily computed and compared with other transmission techniques of similar nature, as summarized in Table 2. In this table, it is shown that the proposed technique gives rise to a signal bit rate of 29.73Gb/s, which outperforms (8- The error propagation-free approach reported in [9], [10] is also applicable in this technique. In this approach, the signal modulation formats taken on each individual subcarrier are compared between the transmitter and the receiver.…”

“…As a combination of the aforementioned three OFDM categories, a DSP-based signal transmission technique called subcarrier index-power modulated optical OFDM (SIPM-OOFDM) has been published in [9], where the combined subcarrier index and subcarrier power acts as an extra information-bearing dimension for carrying additional information bits. In SIPM-OOFDM, subcarriers of high and low powers assigned according to an incoming data sequence are encoded with 8-PSK and QPSK, respectively.…”

A signal transmission technique termed subcarrier index-power modulated optical orthogonal frequency division multiplexing with dual superposition multiplexing (SIPM-OOFDM-DSPM) is proposed and investigated, for the first time, for IMDD PON transmission systems. Compared to previously published similar transmission techniques, SIPM-OOFDM-DSPM not only enables more information bits to be conveyed in the extra information-carrying dimension but also improves the power usage efficiency, performance flexibility and adaptability without increasing DSP and hardware complexity. Detailed numerical simulations of the proposed technique are undertaken to identify optimum transceiver parameters, based on which its performance characteristics are explored. It is shown that over the aforementioned transmission systems, SIPM-OOFDM-DSPM considerably enhances the signal transmission capacity and simultaneously decreases the power penalty, in comparison with other subcarrier-index power-based OOFDM techniques encoded using similar signal modulation formats.

With the emergence of new applications (eg, extended reality [XR] and haptics), which require to be simultaneously served not just with low latency and sufficient reliability, but also with high spectral efficiency, future networks (ie, 6G and beyond) should be capable of meeting this demand by introducing new effective transmission designs. Motivated by this, a novel modulation technique termed as orthogonal frequency division multiplexing with subcarrier power modulation (OFDM-SPM) is proposed for providing highly spectral-efficient data transmission with low-latency and less-complexity for future 6G wireless communication systems. OFDM-SPM utilizes the power of subcarriers in OFDM blocks as a third dimension to convey extra information bits while reducing both complexity and latency compared to conventional schemes. In this article, the concept of OFDM-SPM is introduced and its validity as a future adopted modulation technique is investigated over a wireless multipath Rayleigh fading channel. The proposed system structure is explained, an analytical expression of the bit error rate (BER) is derived, and numerical simulations of BER and throughput performances of OFDM-SPM are carried out. OFDM-SPM is found to greatly enhance the spectral efficiency where it is capable of doubling it. In addition, OFDM-SPM introduces negligible complexity to the system, does not exhibit error propagation, reduces the transmission delay, and decreases the transmission power by half.
