In this project Direct sequence principle based WCDMA transmitter and receiver is implemented in VHDL for FPGA. The digital frequency synthesizer principle is used in generating the carrier signals both at transmitter and receiver modules. The transmitter module mainly consists of symbol generator, ...
VHDL IMPLEMENTATION OF DSSS-CDMA TRANSMITTER AND RECEIVERDDFSDS-CDMALFSRPN codespread spectrumThe DS - CDMA is expected to be the major medium access technology in the future mobile systems owing to its potential capacity enhancement and the robustness against noise. The CDMA is uniquely featured ...
In the proactive FH anti-jamming, the transmitter and receiver proactively hop between channels without verifying state of the channel. Another words, the legitimate transmitter and receiver not needed to detect the presence of a jammer. The legitimate transmitter and receiver in the reactive FH ...
Interestingly, it is even measuring the 3 parts per million difference between the transmitter and receiver clocks in the detected chip rate value. What isn’t rock solid is the actual bit information, which begins to degrade as the noise is increased. But just establishing the parameters of ...
FHSS (Frequency Hopping Spread Spectrum) changes frequencies in a pattern known to both transmitter and receiver, while DSSS (Direct Sequence Spread Spectrum) spreads the signal over a wider frequency band using a specific code. Difference Between FHSS and DSSS ...
