“…As illustrated in Fig.1, the SIPM-OOFDM-SPM operating principle is similar to previously reported SIPM-OOFDM [11], [12], except that considerable modifications are made to relevant transceiver DSP functions that deal with bit allocation/recovery in the newly introduced information-bearing dimension and the conventional subcarrier-information-carrying dimension.

“…Such errors, however, do not propagate across different subcarriers and symbols. As the DSP process adopted for decoding low power subcarriers in the conventional subcarrier-information-carrying dimension is identical to that used in SIPM-OOFDM [11], [12], here attention is thus focused on the high power subcarrier decoding process. For a high power subcarrier, the received complex value after equalization can be written as:…”

“…To address such a challenge and further explore its feasibility for use in IMDD PON scenarios, more recently a new transmission technique termed subcarrier index-power modulated optical OFDM (SIPM-OOFDM) has been proposed [11], [12], in which a combination of both the subcarrier index and subcarrier power acts as an extra information-carrying dimension, where low and high power subcarriers are encoded using quadrature phase shift keying (QPSK) and 8-phase shift keying (8-PSK), respectively. More specifically, when a "1" ("0") bit of an incoming PRBS stream is encountered, the corresponding subcarrier is set at a high (low) power level and subsequently encoded using 8-PSK (QPSK) by truncating following 3 (2) bits from the input PRBS stream.…”

A novel signal transmission technique termed subcarrier index-power modulated optical OFDM with superposition multiplexing (SIPM-OOFDM-SPM) is proposed and investigated, for the first time, in which SIPM automatically creates an information-carrying subcarrier power pattern via assigning a high (low) signal modulation format to a high (low) power subcarrier, whilst SPM passively adds different signal modulation format-encoded complex numbers and assigns the sum to a high power subcarrier. In comparison with conventional OOFDM, SIPM and SPM enable extra information to be conveyed in both the new subcarrier index-power dimension and the conventional subcarrier-information-carrying dimension. In this paper, extensive numerical explorations of SIPM-OOFDM-SPM performance characteristics are undertaken, based on which optimum transceiver design parameters are identified. For IMDD PON systems, it is shown that SIPM-OOFDM-SPM considerably improves the signal transmission capacity, link power budget and system performance tolerances to both chromatic dispersion and fiber nonlinearity.

Subcarrier Index-Power Modulated-Optical OFDM With Dual Superposition Multiplexing for Directly Modulated DFB-Based IMDD PON Systems

A low-signal-modulation format-enabled highly spectrally efficient new transmission technique termed subcarrier index-power modulated optical OFDM with dual superposition multiplexing (SIPM-OOFDM-DSPM) is proposed and investigated, for the first time, in intensity modulation and direct detection (IMDD) passive optical network (PON) systems incorporating directly modulated DFB lasers (DMLs). The DSPM operation passively adds two low-signal-modulation format-encoded complex numbers and assigns the sum to subcarrier index-power modulation (SIPM)-generated low-and high-power subcarriers. Detailed numerical explorations of SIPM-OOFDM-DSPM performances over additive white Gaussian noise channels are undertaken, based on which optimum key transceiver parameters are identified. In comparison with previously published techniques, over simple DML-based IMDD PON systems, SIPM-OOFDM-DSPM considerably improves the signal transmission capacity, system power budget, and performance tolerance to both chromatic dispersion and fiber nonlinearity. The work suggests that SIPM-OOFDM-DSPM is a promising signal transmission technique capable of providing cost-sensitive PON systems with improved transmission capacity, performance flexibility, and adaptability.

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.
