  1. Telecommunication Systems –II Laboratories Review

  2. TLabs 1,2,3:Types of PulseCodeModulation (PCM) • Sampling • Natural Sampling • Sample & Hold • Quantization • Standard step • Differential (DM) • Differential PCM (DPCM) • Delta Modulation

  3. TLab 4,5: Transmit and Receive Filter • Raised Cosine Filter: At the transmitter side for pulse shaping • Matched Filter: At the receiver side for maximum instantaneous SNR values

  4. TLab6: AWGN Channel • Additive White Gaussian Noise • Es/Nο = Eb/N0 +10log10(k) in dB

  5. TLab7: Pulse Amplitude Modulation

  6. TLab8,9: M-PSK,QPSK

  7. TLab8: BER calculation of Gray-coded 8-PSK

  8. TLab9: QPSK

  9. TLab9: M-QAM
