Power Line Communication

1. High transmission rate
2. No need for extra wire. No need for re-wiring.

Hostile transmission environment (Frequency-selective phenomena)

System review:
The backbone of the proposed system is IDMA.

Introduction to IDMA(Interleave-Division Multiple Access)
IDMA is a new method of digital communication that is very powerful and can approach the Shannon limit. For each user, the input data sequence is first encoded and then permutated. The key principle of IDMA is that the interleavers should be different for different users.

To know more details, please read the following paper.

Very interesting post! Get perytons PLC analyzer to analyze power line communication which is well known technology for machine to machine interchange of data.
