CDMA with Joint Modulation

FEC: Convolutional code concatenated with biorthogonal (16,5) modulation. Coherent demodulation. Overall chip rate 160kchips/sec.

(c): All 5 bits in biorthogonal (16,5) modulation for 10 bps, rate 1/2 convolutional code, spreading factor 781.

(b1): 4 of 5 bits in Biorthogonal (16,5) modulation for 10bps, rate 1/2 convolutional code, spreading factor 624.

(a1): 1 of 5 bits in biorthogonal (16,5) modulation for 10bps, rate 1/2 convolutional code, spreading factor 156

(d): All 5 bits in biorthogonal (16,5) modulation for 10kbps, rate 1/5 convolutional code.

(a2): 4 of 5 bits in Biorthogonal (16,5) modulation for 10kbps, rate 1/4 convolutional code.

(b2): 1 of 5 bits in biorthogonal (16,5) modulation for 10kbps, no convolutional code.
