In my point of View Forward Link Channel Parameters are:
* 64 orthogonal Walsh codes per sector to identify channels
* Long code (period 2 42 -1) to scramble data
* DS-SS at 1.2288 Mcps
* Every cell uses the same PN sequence (period 2 15 or 26.67ms) and is identified by a pre-defined offset (64 x n chips)
* Coherent QPSK demodulation
* Diversity
o Time diversity: coding + interleaving
o Path diversity: soft handoff and RAKE receiver
