CDMA with Joint Modulation

FEC: Convolutional code concatenated with Nordstrom-Robinson (16,8) modulation. Coherent demodulation. Overall chip rate 160kchips/sec.

(c): All 8 bits in Nordstrom-Robinson (16,8) modulation for 10 bps, rate 1/2 convolutional code, spreading factor 2000.

(b1): 7 of 8 bits in Nordstrom-Robinson (16,8) modulation for 10bps, rate 1/2 convolutional code, spreading factor 1750.

(d): All 8 bits in Nordstrom-Robinson (16,8) modulation for 10kbps, rate 1/8 convolutional code.

(b2): 1 of 8 bits in Nordstrom-Robinson (16,8) modulation for 10kbps, no convolutional code.
