B2:4-PAM performance: SNR difference between given values of BER For this question, the following Simulink blocks will be used Tx Bemouli 4-PAM 4-PAM AWGN Error Rate Bemoulli Binary Generator M-PAM Error Rate Calculation AWGN Baseband Connect the blocks as illustrated Tx Error Rate Calculation Bemouli 4-PAM AWGN Rx Error Rate Calculation Binary Source M-PAM Modulator M-PAM AWGN Channel Display (BER) Parameter setu Binary Source: Probability of zero: 0.5 I Sample time: 1e-6 I Samples per frame:2 PAM Modulator: M-ary number: 4| Input type: Bit PAM Demodulator: M-ary number: 4 I Output type: Bit AWGN Channel: Initial seed: randseed | Mode: Signal to noise ratio (Es/No) | Es/No (dB): | Symbol eriod (s): 2e-6 Error Rate Calculation: Output data: Port | Stop Simulation | Target number of errors: 200 | Maximum number of symbols: 1e6 Question: At first, find the value of Es/No (dB) in AWGN Channel so that BER value seen on Display (BER approximately equals to BER1. Then decrease the BER value to BER2 by changing the value of Es/No (dB) in AWG hannel What is the difference in Es/No (dB) to move BER from BER1 to BER2 for the following cases? Case BER1 0.02 0.02 0.01 0.02 0.01 BER2 0.001 0.002 0.001 0.004 0.004 4 5 B2:4-PAM performance: SNR difference between given values of BER For this question, the following Simulink blocks will be used Tx Bemouli 4-PAM 4-PAM AWGN Error Rate Bemoulli Binary Generator M-PAM Error Rate Calculation AWGN Baseband Connect the blocks as illustrated Tx Error Rate Calculation Bemouli 4-PAM AWGN Rx Error Rate Calculation Binary Source M-PAM Modulator M-PAM AWGN Channel Display (BER) Parameter setu Binary Source: Probability of zero: 0.5 I Sample time: 1e-6 I Samples per frame:2 PAM Modulator: M-ary number: 4| Input type: Bit PAM Demodulator: M-ary number: 4 I Output type: Bit AWGN Channel: Initial seed: randseed | Mode: Signal to noise ratio (Es/No) | Es/No (dB): | Symbol eriod (s): 2e-6 Error Rate Calculation: Output data: Port | Stop Simulation | Target number of errors: 200 | Maximum number of symbols: 1e6 Question: At first, find the value of Es/No (dB) in AWGN Channel so that BER value seen on Display (BER approximately equals to BER1.
