Abstract :
A statistical analysis of ACS factors for an UTRA mobile terminal receiver is presented. A variable ACS channel filter is also described and analysed. UTRA-TDD has an average ACS of 19 dB corresponding to an average filter length of 11 taps. It is 75 percent more efficient compared to the specification ACS of 33 dB, which corresponds to a filter length of 41. UTRA-FDD has an average ACS of 16.26 dB corresponding to an average filter length of 7 taps. This is a greater efficiency improvement of 82 percent compared to the specification. The analysis clearly demonstrates that a receiver channel filter with a variable ACS in the mobile terminal is highly efficient compared to a fixed ACS filter that meets the specifications.
