CDMA Modulation for Communication System Environment using Frequency Hopping Spread Spectrum

Abstract

In this paper, an overall framework for a joint Special emphasis is placed on the communication segment of
the sensing system at 85 GHz. Code division multiplexing using frequency hopping spread spectrum signals is
implemented at 85 ghz to take advantage of reduced interference between ambient communication. The framework,
which spans the entire chain of signal processing, mat lab is enabled, explained, and simulated using data networking. A
template, able to scatter, fraud detection, including radio frequency-block and synchronization non-idealities are built up
and analyzed. Also, the implementation of a channel model is into the Win Prop technology and embedded into the
simulation of simu link. In the previous paper, they implemented the code division multiple access using a direct
sequence spread spectrum at 77ghz for secure communication. Because of using 77ghz for the direct sequence spread
spectrum, there will occur noise distortion and interference in the communication system. So that there will be poor
system communication between transmitter and receiver. To overcome these problems, our paper explains the
implementation of code division multiple access using frequency hopping spread spectrum for better and secure
communications. By using this frequency-hopping spread spectrum technology, we can reduce the noise distortion and
interference between the transmitter and the receiver. So that our system will be in proper condition to transmit the
signals in the same range of frequency without any interference and distortion. FHSS systems can allow a higher
aggregate bandwidth for coverage because FHSS provides more channels in the same range of frequencies. In accordance
with the bit-error-rate, the module is assessed. By creating white Gaussian additive noise. The attribute is proven to
reconcile the theoretical assumptions with the outcomes. By organizing a Rake-Receiver, the system is further boosted
with structure configuration without any distortions.
