Abstract
Successful development of broadband over powerline is obviously a potential solution for wired communication systems with the existence of the powerline network. From past research, it is known that the powerline channel suffers from multipath fading, frequency selectivity and also impulsive noise. Multi Carrier Code Division Multiple Access (MC-CDMA) is a promising solution for an impulsive noise powerline channel. This paper starts with the MC-CDMA transmitter structure and focuses on powerline channel model, noise model and various types of available channel estimators. The main concern in Powerline Communication Systems is the existence of impulsive noise. The proposed pilot assisted channel estimation uses the modified least square estimator that reduces the effect of impulsive noise in the estimated channel impulse response.

Summary
Power line communication or power line carrier (PLC) is a system for carrying data on a conductor used for electrical power transmission. There are some factors that contribute to the distortion and noise in the received signals in power line networks These factors are mainly the topology of the main network, multipath signal propagation, cable losses as well as the colored noise [4]. Multi carrier code division multiple access (MCCDMA) system is well known for its effectiveness in combating multipath and intersymbol interference (ISI) effects. It can accommodate very high data rate transmission over hostile channel. Channel estimation for MIMO_OFDM has been investigated in [9], which can be used for up-link MC-CDMA systems. The aim of this paper is to design an improved channel estimator for power line communication systems to support next-generation multimedia services.
