In this paper, transmission through large intelligent surfaces (LIS) that
intentionally modify the phases of incident waves to improve the signal quality
at the receiver, is put forward as a promising candidate for future wireless
communication systems and standards. For the considered LIS-assisted system, a
general mathematical framework is presented for the calculation of symbol error
probability (SEP) by deriving the distribution of the received signal-to-noise
ratio (SNR). Next, the new concept of using the LIS itself as an access point
(AP) is proposed. Extensive computer simulation results are provided to assess
the potential of LIS-based transmission, in which the LIS acts either as an
intelligent reflector or an AP with or without the knowledge of channel phases.
Our findings reveal that LIS-based communications can become a game-changing
paradigm for future wireless systems.
