Proposed Title :

High Efficient Technique of Line Coding for Channel Equalization using the concept of Integrated Pulse Width Modulation and Consecutive Digit Chopping.

Improvement of this Project:

• • To develop a line coding technique for Integrated Pulse Width Modulation Technique and Consecutive Digit Chopping method in order to increase the efficiency of wire line communication.

  • To develop a VHDL code for integrated pulse width modulation technique with consecutive digit chopping technique in 64 bit of data for transmission and reception.

Software implementation:

• Modelsim
• Xilinx

Proposed System:

In telecommunication system, a line coding is a pattern representation of voltage, current, or photons in digital format and used to transmit a digital data  down a transmission line.   This paper proposes the new design concept of line coding techniques with high efficient for equalizing the channel with use of two techniques of line coding such as  integrated form of  Pulse Width Modulation (iPWM) and (CDC) Consecutive Digit Chopping.  The main aim of the proposed line coding technique is to equalizing the lossy wire line channel in order to attain a energy efficient wire line communication.  The proposed system overcome the limitations that are faced by the existing pulse width modulation technique and Manchester encoding technique.  And the existing system of line coding technique of integrated form of pulse width modulation technique and consecutive digit chopping technique is implemented in the single bit with 4 different phase shifting technique.  Therefore, the efficiency of data is low.  Thus, the proposed system of line coding technique proposes the multi bit data transceiver with four different phase shifting technique achieves a better and high efficient in wire line communication.  Finally, implemented the proposed system of line coding technique in VHDL and synthesized using  XILINX and shown the comparison in terms of delay, power and area reports.
