With neat diagram explain reverse CDMA channel
written 3.0 years ago by |
The CDMA reverse channel is fundamentally different from the forward channel. It employs OQPSK rather than QPSK used in the forward channel. OQPSK is closer to a constant envelop modulation. This constant modulation technique provide for a more power efficient implementation of the transmitter at the MS. The QPSK modulation …
