Abstract: 

We Design CDMA Transmitter & Receiver forSecure Transmission of Message Signal Between them Using Walsh Sequences. As Walsh Sequences is a Random Signal/High Frequency Carrier Signal which Generates by Walsh Sequence Generator. Walsh Sequence Generator generates a Serial In Serial Out Signal in Binary Form. And Further It Passes with Input Signal in Terms of Runtime Walsh Sequences. Walsh Sequence is also used for Error Detecting and Error Correcting Mechanism. It used For Secure andEfficiant Communication. If any Error Occure during Transmission, Walsh Sequence Troubleshoot and Correct it and Passes to those Receiver whichever Required. The Further investigation consider FPGA parameters like Speed and PowerDissipation..Here we design a system with less time delay so that Speed of Transmission System is more And Power Dissipation is little as Compared to Previous One. The Above Design is Implemented in VHDL Code.The Design found their uses in many popular applications like multiuser communications such as CDMA, WCDMA, VLSI Testing, Pattern Recognition as well as image and signal processing.
