In initalizing the object, it performs the /following operations / 1. Initializes the slot format configurations for the DPCH / 2. Initializes the slot format configurations for the S_CCPCH / 3. Initializes the slto format configurations for the PDSCH / 4. Generates the channelization code for each of the SF required for the transmitter / 5. Generates the overal scambling sequence (the scrambling codes will come from this sequence / 6. Completes the configuration of all of the remaining physical channels. This includes / a. Allocation of Channelization Codes / b. Allocation of Srambling Codes / c. Setting the STTDflag / d. Setting the TPC command / 7. Determines the timing offsets for each of the frames / 8. Computes the relative gains for each of the frames / 9.
