Abstract
Visible Light Communication (VLC) is the hope for keeping up the rapid increase of user’s data demands. VLC provides high-speed data connections. However; it suffers from limited optical bandwidth, and performance decline due to either inter-symbol interference (ISI) or co-channel interference (CCI). In this paper, CCI is managed by using Angular Diversity Receiver (ADR) with a limited field of view to reduce the number of interfered signals. After that least-square (LS) channel estimation with maximum-likelihood (ML) equalizer is used to resolve the interfered signals. The bit-error-rate (BER) is calculated at different room positions and receiver’s heights. The simulation results appear that the proposed scheme BER performance has been enhanced at all positions of the ADR.
