... The forward IS95 channel consists of several code channels: - The pibt channel - It is always transmitted by the BS on each active forward CDMA channel. It is unmodulated spread sequence signal (i.e. it does not contain spreading by the short walsh Hadamard code). The pilot tone is a PN-sequence wh ...
