 The development of educational kit must be compiled on how to prepare undergraduate students in the engineering field in following the new trends globally and becoming an alternative to the technical education system based on practical approach. The primary motivation for this research is to design and implement the visible light communications (VLC) educational toolkit, especially in the analog front-end part. It consisted of six kits (transimpedance amplifier, pre-amplifier, DC-offset remover, analog filter, and AGC) in which each kit has one practicum task. There are six tasks and one task for the project by integrating these kits. The undergraduate students can use this educational kit to investigate the physical layer in a VLC system. It provides a low-complexity educational kit, so this is becoming an alternative as supplement course offered in this field. Then, it has a simple design and user-friendly. The development of educational kit must be compiled on how to prepare undergraduate students in the engineering field in following the new trends globally and becoming an alternative to the technical education system based on practical approach.

Data Rates

Spatial Modulation is a kind of spatial multiplexing schemes conveying information by the location of transmit antennas and spatial modulation (SM) along with OFDM can be applied to visible light communications for higher data rates. The closed form of symbol error rate (SER) in optical SM-OFDM communication system is derived in this paper. SER is a convex function of power allocation coefficients, therefore there exist optimal allocation coefficients minimizing SER. The optimal allocation coefficients are derived for different channels and numbers of transmit antennas. Analytical results are validated by Monte Carlo simulation results and these results show that a significant SER improvement is obtained by using the power allocation. In addition, the optimal allocation coefficients are affected by the channel and number of transmitters.
