Data rate (bit/s)
II. R-TCH performance in multipath fading without Closed-Loop power control
The performance of the demodulation of the Reverse Traffic Channel in a multipath
fading environment is determined by the frame error rate (FER) at specified Eb/N0
value.
FER of 4 possible data rates should be calculated respectively. With 95% confidence,
the FER for each data rate shall not exceed that given by linear interpolation on a log10
(FER) scale between the two values given in Table A-13 and Table A-14.
The test value of Eb/N0 assumes the average value of Eb/N0 in two RF input ports.
During the test, the reverse service channel Eb/N0 of each RF input port adopted is
within the limits specified in Table A-12.
The configurations of standard channel simulator are given in Table A-10; and the
channel models of the R-TCH receiving performance test in multipath environment are
listed in Table A-11.
