- •
We include the effect of laser phase mitigation and how it affects system performace.
- •
We highlight several aspects of the nature of the coherent optical wireless channel
- •
We discuss the ambient light coupling efficiency in coherent receivers
- •
Using Gaussian optics, we provide a detailed framework for the power budget analysis using ABCD matrix theory.
- •
We highlight the relation between the transmitter power receiver area product PTAr and the overall system performance.
- •
We compare the performance of coherent and IM/DD optical wireless
- •
Our results indicate that 2 Gb/s and 10 Gb/s data rates can be easily sustained at 3 m distance over a circular coverage area of 1 m radius using Class-1 eye safe lasers.
