  40. Additional Bits Additional Bits Error Correction Control Information • Channel • Ground Station • Power • Identity • Billing

  41. Modulator

  42. 0 Bit in/Wave out

  43. 1 Bit in/Wave out

  44. Colored Balls 1

  45. Colored Balls 2

  46. 6000 Hz Available 6000 Hz Available Bandwidth Nyquist’s Theorem: Can transmit 4000 symbols per second through a 6000 Hz channel

  47. Colored Balls 2 Nyquist’s Theorem: Can transmit 4000 symbols per second through a 6000 Hz channel

  48. BPSK 4000 < 8000 • BPSK: 1 Bit Per Symbol • 4000 Bits Per Second (bps) • 4000 bps < 8000 bps (Vocoder rate) • BPSK

  49. QPSK 8000 BPS • QPSK: 2 Bits Per Symbol • 2 X 4000 = 8000 Bits Per Second (bps) • 8000 bps = Vocoder rate • Need more bits for error correction and control! • QPSK

  50. 8PSK 12000 BPS • 8PSK: 3 Bits Per Symbol • 3 X 4000 = 12,000 Bits Per Second (bps) • 8000 bps + 4000 bps • Vocoder rate + Error Correction and Control • 8PSK
