Abstract :
The theoretical BER is calculated for downlink in UMTS including interpath interference and multiple access interference. The analog interface to the digital receiver is analyzed and an architecture including AGC and ADC is suggested. It is further analyzed that an ADC with 4-5 bit and sampling of 4 times the chip rate will give an acceptable performance within 0.2 dB from the theoretical performance
