so, i want to implement in hardware also.(not in simulink) have u use this block in system generator. Shark Additive White Gaussian Noise (AWGN) Core v1.0 2 www.xilinx.com DS210 October 30, 2002 1-800-255-7778 Product Specification Functional Description The AWGN core generates white Gaussian noise using a combination of the Box-Muller algorithm and the central limit out = awgn(in,snr,signalpower,seed) specifies a seed value for initializing the normal random number generator that is used when adding white Gaussian noise to the input signal. For information about producing repeatable noise samples, see Tips. Modern mobile devices and base stations need to cope with varying transmission conditions.

### AUTONOMOUS DETECTION OF VACANT FREQUENCY

The output level can be set as Noise Density or Noise Power in a selectable bandwidth.

Depending on the options the R&S ® SMW200A vector signal generator is equipped with, up to eight independent noise sources are provided. AWGN channel model In order to simulate a specific SNR point in performance simulations, the modulated signal from the transmitter needs to be added with random noise of specific strength. The strength of the generated noise depends on the desired SNR level which usually is an input in such simulations. In practice, SNRs are specified in dB. out = awgn (in,snr,signalpower,seed) specifies a seed value for initializing the normal random number generator that is used when adding white Gaussian noise to the input signal. For information about producing repeatable noise samples, see Tips.

Firstly, AWGN generator is designed with floating point in C++ language. Then fixed-point model is developed in C++. The means and standard deviations of the designs with fixed point and floating point are tested and it is proved that designs have normal distribution.

New The MG3710E Vector Signal Generator is a best-of-class, high-function, signal generator with excellent RF and baseband performance. Up to two RF output connectors can be installed each with two built-in waveform memories to output two combined modulation signals from each RF connector for a maximum of four modulation signal outputs. PNG7000 Analog AWGN Noise Generator . The PNG7000A Series instruments generate white Gaussian noise (AWGN) and provide a summing input to control signal-to-noise (SNR) or carrier-to-noise (CNR) for bit-error-ratio (BER) testing. The output can also be used as a source for Jitter applications. Industry’s first noise solution for testing VDSL2 Vectoring. AWGN signal generators are hardware cost-effective, thus this ar- ticle presents a simple and inexpensive way to build white noise generators.
