Table 5.17 Test parameters for Adjacent Channel Selectivity Parameter Level DPCH_Ec dBm/3.84 MHz dBm/3.84 MHz -92.7 Ioac (modulated) dBm/3.84 MHz Fuw (offset) The (CDPCH_Ec/Iq)TDD has 0 dB as test parameter for the adjacent channel selectivity. 5.4.4 Blocking The blocking characteristic indicates the measure of the receiver's ability to receive a wanted signal at its assigned channel frequency in the presence of an unwanted interfer- ence on frequencies other than those of the spurious response or the adjacent channels. The unwanted input signal shall not cause a degradation of the performance of the re- ceiver beyond a specified limit, and the blocking performance shall apply at all frequen- cies except those at which a spurious response occur. The BER shall not exceed 0.001 for the parameters specified in Tables 7.6 and 7.7. For Table 7.7 up to (24) exceptions are allowed for spurious response frequencies in each assigned frequency channel when measured using a 1 MHz step size.
