This document summarizes research analyzing the performance of an iterative IDMA (interleave division multiple access) scheme for power line communication. The IDMA model simulated uses BPSK modulation with k simultaneous users on a single-path power line channel. Convolution coding with a rate of 1/2 was used at the transmitter. Simulation results showed that increasing the data length and using coding improved the bit error rate performance of the IDMA system over power line channels. Coded IDMA achieved a lower bit error rate than uncoded IDMA.

Abstract
Power line distribution networks are mainly used for electrical power supply. The ever-increasing demand of
low cost telecommunication, broadband and access to internet services has applied a driven force leading to
further research in the field of power-line communication. Different multiplexing techniques, OFDM, CDMA,
MC-CDMA, has been already used with power line communication. In this paper coded IDMA is being used
with power line communication also the simulation and result has been described.
Keywords: CDMA.IDMA,MC-CDMA,OFDM,Power line communication.
1. Introduction
With the advent of technology the need of low- cost broadband communication has been increased so many folds,
also becomes the driven force leading to further research in the field of power line communication. Power line
used for transmission of broadband data has been under extensive studies during last year. Today due to
increasing demand of networking in home, offices, buildings, industrial organizations etc, the power lines are
considered as a medium for high speed data(>2Mbps) transmission[Esmailian, Lindell ]. PLC Broadband
technology is capable of transmitting data via the electrical supply network, and therefore can extend an existing
local area network or share an existing Internet connection through electric plugs with the installation of specific
units. The principle of PLC consists in superimposing a high frequency signal (message signal, 1.6 to 30 MHz)
at low energy levels over the 50 Hz electrical signal [Y. H. Ma]. This second signal is transmitted via the power
infrastructure and can be received and decoded remotely. Thus the PLC signal is received by any PLC receiver
located on the same electrical network. In order to transport the PLC signal on electrical wiring, the line
frequency (for example, 110 V/60 Hz) of the electrical circuit is supplemented by a modulated signal of low
amplitude around a centre frequency (carrier frequency)[ Y. H. Ma].
Various broadband power line communication (PLC) solutions based on OFDM technology are currently exists
[Xavier Carcellem]. CDMA (Code Division Multiple Access) modulation is a type of spread spectrum
modulation used in some PLC solutions because its successful application of CDMA in various communication
areas suggests that it is a good candidate in broadband power line communications as well. There have been
some researches done for evaluating the performance of OFDM and CDMA systems in power lines [P. L. So, 5,
P.L. Katsis]. The performance analysis of these different models has been developed by close formulas and
verified by simulation results[Xavier Carcellem Y. H. Ma, P. L. So, S.M.Navidpour, P.L. Katsis].
In this paper we have simulate the power line channel in order to measure the efficiency of a wired iterative
interleave code division multiple access system with rate ½ convolution coding.
2. IDMA System Characteristics
Interleave division multiple access (IDMA), it is recently proposed multiple access scheme in which user-
specific interleavers are adopted as the only mechanism for user separation. Since interleaving is the only
mechanism for user separation that’s why called IDMA. IDMA can be regarded as a particular case of chip
interleaved CDMA. This scheme inherits many advantages from CDMA such as dynamic channel sharing,
mitigation of cross-cell interferences, asynchronous transmission, and ease of cell planning. It also allows a low
complexity multiple user detection techniques applicable to systems with large numbers of users in multipath
channels. As so, IDMA inherits many advantages of CDMA. IDMA fulfil all the requirements of advanced 4G
wireless communication system that’s why it is widely being deployed now days and is going through many
researches also being used with wired communication.](https://image.slidesharecdn.com/performanceanalysisofiterativeidmaschemeinpowerlinecommunicationusingrandominterleaver-130619222624-phpapp02/85/Performance-analysis-of-iterative-idma-scheme-in-power-line-communication-using-random-interleaver-1-320.jpg)
