In this paper we compare bit-error rate (BER) and signal to noise ratio (SNR), obtain simulation results and made comparison among different transmission methods which are Channel Inversion (CI), Block Diagnolization(BD), DirtyPaper Coding (DPC) and Tomlinson-Harashima Pre-coding (THP) ...

These techniques are selected on the basis of factors like low Signal to Noise Ratio (SNR), low Bit Error Rate (BER), complexity of design and final cost of the product etc. This paper will focus on the performance comparison of theoretical and simulated BER of above three schemes and ...
The user can test the BER, histogram and SNR, on the selected channel, in NRZ and PAM4 modes. Figure 32: BER analysis tab Figure 33: Histograms in PAM4 mode ` Figure 34: SNR in PAM4 mode This BERT gives the user the possibility to insert errors by enabling the error insertion option...
Based on this analysis a PSK modulation scheme for SDR is proposed to pick the constellation size that offers the best reconstructed signal quality for each average SNR. Simulation results of signal transmissions confirm the effectiveness of our proposed PSK modulation scheme. The performance of the ...
The aim to capture enough signal energy to maintain an acceptable output signal to noise ratio (SNR) dictates a very complicated rake structure with a large number of fingers. Channel shortening or time domain equalizer (TEQ) can simplify the rake receiver design by reducing the number of ...
aIn Figure 7, the Bit Error Rate (BER) of the NCCR method versus SNR has been plotted for various numbers of iteration. As can be seen, at , if the clipping and filtering are applied, 9 dB more power is needed to achieve the same BER as the case where there is no clipping at ...

analogy in other forms of recording--it is found that contiguous same-state pixels whatever their origin--whether made up of bits from a common codeword or not--in-line or in two-dimensional groups increase error rate and reduce SNR, so that expected recording densities are effectively ...
