Round 1

Reviewer 1 Report

Dear authors,

Thank you for submitting this manuscript. You propose a CDMA scheme for the application of visible light communication. I do not see obvious flaws in the architectural design, following analysis and the conclusion section. However, the introduction part needs more supporting references.

  1. Line 28-29: "because it can provide additional spectrum resources" requires a reference.
  2. Line 29-30: please add references to support "rapid development of high-power LEDs".
  3. Line 31-32: "LED devices can be used as data transmitters without losing their main functionality as lighting and signaling device" requires a reference.
  4. Line 32-34: please add references to support the advantages of VLC compared with radio wave communication.
  5. Line 35-37: please add supporting references to the applications of VLC.

Reviewer 2 Report

This paper proposed an optical CDMA system using inverted modified prime sequence codes with multi-user interference cancellation schemes incorporated. The proposed system is expected to provides higher average light intensity and lower normalized fluctuation without losing the capabilities of channel multiplexing. Overall it is interesting and can be accepted provided that some minor revision being made.

1. Some statement in the paper may be not in the proper position. For example, the statement about the partly presentation may be moved to the acknowledgement. The last paragraph of the Conclusion may be move to the discussion part.

2. It is claimed that the capability of channel multiplexing can be maintained. It may be better to add some experiment or at least some similar reported results to validate this conclusion. Also, the potential working bandwidth, communication distance may need to be discussed.
