“…The DP-MZM is polarized to its minimum transmission bias point to realize optical carrier suppression (OCS) modulation and the used parameters are shown in Table 1. This MZM is driven by the combined signals to modulate the optical carrier and to multiplex the subcarriers as depicted in inset (b) [6,11].…”

“…Indeed, RoF allows the transport of multiple RF signals over single optical fiber, from central office to base station. Various techniques have been described to transport MIMO signals over fiber [2][3][4][5][6][7]. Among them, we find the polarization-division-multiplexing (PDM) [2,3], optical subcarriers multiplexing [4][5][6], or PDM with optical heterodyne up-converter at base station [7].…”

“…We have used the model of Desktop environment which is a typical office desktop and computer cluster [10]. Compared to previous works [5,6] and considering in this paper a more precise channel model, we propose in this work a global architecture including a hybrid system in the optical and wireless regimes for communications around 60 GHz. The behavior prediction of such system is carried out by a global simulation using the real characteristics of the functions: baseband, optical/RF and transmission environment.…”

This paper proposes a new scheme for the generation and transmission of a MIMO-OFDM signal over optical fiber using a single local oscillator (LO) at 15GHz. This technique is based on subcarrier multiplexing and Optical Carrier Suppression (OCS) modulation using both Dual-Parallel Mach-Zehnder Modulator (DP-MZM) and Dual-Drive Mach-Zehnder Modulator (DD-MZM). DP-MZM is used to multiplex the MIMO-OFDM signals while DD-MZM is used to generate the 90GHz signal by quadrupling. The realistic and global simulation of the complete system is performed to predict the behavior of a Radio over Fiber (RoF) system prior to its realization. The optical and wireless channels are based on Single Mode Fiber (SMF) and TripleS and -Valenzuela (TSV) models, respectively. We have exploited the allocated 7GHz in the 60GHz band for unlicensed use and we have successfully achieved 50km SMF followed by 3m wireless link at 70Gb/s. In comparison with traditional methods, the technique proposed combines better performance at relatively low-cost.

“…Generally, the threshold BER is dependent on the type of transmission, for instance, the voice data transmission may tolerate the threshold BER as high as 10 −2 , though for video data transmission, more stringent BER requirements need to be applied [35]. In the proposed work, the threshold BER is kept at forward error correction (FEC) limit of 10 −3 …”

Radio over fiber (RoF) is an indispensable technology for the amalgamation of microwave‐ and optical communication, which facilitates a flexible access‐network infrastructure proficient to endow with broadband wireless connectivity over an extensive assortment of applications. Achieving ample spectral efficiency in conjunction with excellent link reliability is the austere menace to the design of such prospect‐integrated systems. Moreover, amalgamation of multiple‐input multiple‐output (MIMO) technology with multicarrier multiplexing (MCM) such as orthogonal frequency division multiplexing (OFDM) is a proficient contender for supporting such next‐generation RoF‐based static‐ and mobile‐wireless systems. Earlier, the MIMO‐based multicarrier RoF systems are limited to the use of fourth‐order spatial diversity (2 × 2 antenna package) using the Alamouti code. Subsequently, the authors investigated the aptness and impetus of such integrated multicarrier RoF systems to provide a reliable and spectrally efficient system and proposed an orthogonal space‐time block code (OSTBC) equipped MIMO‐OFDM‐RoF system by incorporating higher order spatial diversity in conjunction with QAM (Quadrature Amplitude Modulation) schemes. The proposed work is carried out for NLOS (non‐line of sight) and LOS (line of sight) scenarios. Furthermore, the demonstrated work elucidates a relative QoS (Quality of Service) explorations of sixth (3 × 2 antenna package) and ninth order spatial diversity (3 × 3 antenna package) and recommend the optimal antenna package as per the requirements of the proposed integrated system in the demonstrated scenarios.
