Abstract
In this letter, we propose a multidimensional modem design based on two-level coding in the Gosset lattice $\mathbf {E}_{8}$ for high-rate low-latency peak-limited visible light communication. For low implementation complexity, a simple constellation mapper and a fast maximum-likelihood receiver are developed for our proposed constellation as well. Simulation results show our proposed scheme has about 2 dB performance gain and less latency as compared to the commonly-used pulse amplitute modulation at neglectable complexity cost.
