چکیده
Multiuser detection technique has been applied for capacity enhancement in the presence of loading, voice activity, sectorization, inter & intra interference in multicell scenario of third 3G WCDMA system. In CDMA based system, each user transmits a data sequences spreaded by a code. This code is Unique to the mobile station (MS) and base station (BS) on both uplink and downlink. The present paper deals with capacity in term of number of user in single and multicell environment in the presence of capacity influencing factor at a constant power of the base station in a CDMA based system operating in downlink FDD mode at 5 MHz bandwidth

متن کاملA +32 dBm 1.85 GHz class-D outphasing RF PA in 130nm CMOS for WCDMA/LTE
This paper presents a Class-D outphasing RF Power Amplifier (PA) which can operate at a 5.5 V supply and deliver +32 dBm at 1.85 GHz in a standard 130nm CMOS technology. The PA utilizes four on-chip transformers to combine the outputs of eight Class-D stages. The Class-D stages utilize a cascode configuration, driven by an AC-coupled low-voltage driver, to allow a 5.5 V supply in the 1.2/2.5 V ...
