What is Forward Channel Modulator (Spreading)? rohit 22-May-2008 05:10:10 AMComments I think Coherent QPSK demodulation, Diversity, Time diversity: coding + interleaving, Path diversity: soft handoff and RAKE receiver. Posted by HamidAliKhan * Identical I, Q signals; but different I, Q PN sequences (short code). * Transmitted power is reduced by 3, 6, or 9 dB for variable data rates at 9.6 k, 4.8 k, 2.4 k, and 1.2 kbps. * QPSK modulation. * Coherent QPSK demodulation. * Diversity. * Time diversity: coding + interleaving. * Path diversity: soft handoff and RAKE receiver.
