CDMA Multiplexing

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

(C): 100% of chips for 10bps rate, rate 1/2 convolutional code, spreading factor 2500.

(B1): 80% of chips for 10bps rate, rate 1/2 convolutional code, spreading factor 2000.

(A1): 20% of chips for 10bps rate, rate 1/2 convolutional code, spreading factor 500.

(D): 100% of chips for 10kbps rate, rate 1/5 convolutional code.

(A2): 80% of chips for 10kbps rate, rate 1/4 convolutional code.

(B2): 20% of chips for 10kbps, no convolutional code.
