The reverse link decoder consists of an R-FCH decoder, R-SCH decoder, and R-DCCH decoder.
Note that the R-FCH decoder requires an additional operation (i.
The data rate on the R-FCH is variable, with the ability to change on a frame-by-frame basis.
For simplicity, the term "Code Channel" is used here to represent the R-FCH, R-SCHI, R-SCH2, or R-DCCH.
For instance, when the mobile station is transmitting with Radio Configuration 5 (rateset 1) on the R-FCH at data rate 0, R-DCCH at data rate 0, R-SCH 1 at data rate 4, and R-SCH2 at data rate 5, Multiple_Channel_Adjustment_Gain for every Code Channel can be derived from its associated Pilot_Reference_Level as shown in Table 5.
t], which is defined as the ratio of the combined received energy per bit to the effective noise power spectral density on the R-PICH, R-FCH, R-SCH1, R-SCH2, or R-DCCH at the receiver base station antenna connector .
The pwr_fch is the output power on the R-FCH calculated from Eq.
We observe that the R-FCH performs better than the R-SCHs despite the fact that the R-FCH has smaller transmit power (P.
t] on the R-SCHs is smaller by about 1 than the R-FCH as shown in Fig.
