Flexible MultiCAP Modulation and its Application to 850 nm VCSEL-MMF Links

“…Simulations results validate the feasibility of the proposed scheme with bit rates over 100 Gb/s by using state-of-the-art electronics, e.g. super high-speed digital to analog converters (DACs) [20], [21]. As a proof of concept, we validate its operation in 850 nm VCSEL based data interconnect up to 40 Gb/s, showing all its key advantages.…”

Ultra‐wideband technology: Prospective solution for 5G ultra‐small cell networks

“…To mitigate this impairment, MB‐CAP has been proposed for wireless and optical links, achieving high spectral efficiencies over large bandwidths 20–25,30,31 . By splitting the spectrum into sub‐bands, MB‐CAP modulation enables the use of bit‐ and power‐loading techniques for each band independently, 20–25,30,31 according to the signal‐to‐noise ratio (SNR) and channel conditions over the frequency range of each band. Thus, with an adequate number of bands, non‐flat frequency responses, for example, uneven antenna gain and non‐flat frequency response of devices, can be alleviated to maximize spectral efficiency.…”

“…Given the advantages of CAP modulation, its multiband scheme (multiband CAP [MB‐CAP]) was developed and first introduced for fiber‐optic links, 20 demonstrating its flexibility to adapt to the large bandwidths of optical links, while achieving record data rates. In addition, MB‐CAP modulation has some advantages over MB‐OFDM, such as a lower PAPR, maximizing the power amplifiers efficiency, and a lower computational complexity 20–25 . Thus, the flexible nature of MB‐CAP modulation is highly suitable for UWB wireless communication systems, allowing to adjust the power and bandwidth used to comply with a variety of current regulatory UWB standards 6–8…”

Nonorthogonal Multiple Access and Carrierless Amplitude Phase Modulation for Flexible Multiuser Provisioning in 5G Mobile Networks

“…In order to mitigate this impairment, the multi-band CAP (multiCAP) has been proposed for wireless and optical links, achieving high spectral efficiency over large bandwidths [23], [24]. By splitting the spectrum into subbands, multiCAP modulation enables the use of bit-and power-loading techniques for each band independently [18], according to its signal to noise ratio (SNR).…”
