In particular: Abstract: patial Modulation (SM) and Multi-Set Space-Time Shift-Keying (MS-STSK) are capable of striking a flexible design trade-off between the multiplexing and diversity gains attained. These techniques can also be combined with beamfoming for the sake of supporting reliable millimeter wave (mmWave) commu- nications. In this treatise, we propose a Radio over Fiber (RoF) downlink network relying on SM and MS-STSK combined with beamforming and up-conversion to mmWave carrier frequencies, whilst using all-optical processing. In the proposed RoF system, most of the digital processing of the baseband SM and MS-STSK is carried out by the Central Unit and the implicitly carried bits of SM/MS-STSK, such as the antenna index selection and dispersion matrix selection bits, are recovered by the remote radio port of our RoF network for creating a multi-functional Multiple-Input Multiple-Output (MIMO) arrangement. As detailed in [1], the classic modulated bits are conveyed by the radio signal, without requiring any additional Analogue-to-Digital Conversion (ADC) and Digital-to-Analogue Conversion (DAC) before transmission from the antennas. Moreover, RoF-aided techniques are invoked for achieving optical processing aided beamforming and optical up-conversion to a mmWave carrier frequency. Thus, we invoke RoF techniques for the generation of our SM/MS-STSK signal with the aid of optically up-converted millimetre wave beam- forming without using any electronic oscillators, mixers or phase shifters. Furthermore, our RoF-aided system’s BER performance is similar to the conventional all-electronic SM/MS-STSK scheme.
