Without delay compensation, the **BER computation is meaningless.decDelay** = 2*traceBack; % Decoder delay, in bits [numErrors, ber] = ... Pulse Amplitude Modulation (4-PAM) In 4-PAM modulation, the symbols are used for transmitting information. Its ideal structure is shown in the picture below with H r {\displaystyle \scriptstyle H_{r}} the receive filter's frequency response: Multiplying by a cosine (or a sine) and by a low-pass Simulate the system. news
