Analysis of Antenna Types Performance in Mobile Phone Base Station

Performance of a Base Station Feedback-Type Adaptive Array Antenna with Mobile Station Diversity Reception

In this paper, Bit Error Rate (BER) performance of Feedback-type Adaptive Array Antenna (AAA) in Frequency Division Duplex/Direct Sequence Code Division Multiple Access system (FDD/DS-CDMA) with Mobile Station (MS) reception diversity will be investigated. The results include the effects of maximum Doppler frequencies (fd) and antenna element spacing at Base Station (BS) under flat fading and f...

Safety Issues of Mobile Phone Base Stations

Short-Term Exposure to Mobile Phone Base Station Signals

Individuals who report sensitivity to electromagnetic fields often report cognitive impairments that they believe are due to exposure to mobile phone technology. Previous research in this area has revealed mixed results, however, with the majority of research only testing control individuals. Two studies using control and self-reported sensitive participants found inconsistent effects of mobile...

Performance Evaluation of MIMO Base Station Antenna Designs

Cellular standards like the third generation partnership program (3GPP) long term evolution (LTE), ultra-mobile broadband (UMB), high speed downlink packet access (HSDPA) and IEEE 802.16e (WiMAX) support multiple-input multiple-output (MIMO) wireless communication technology. MIMO uses multiple antennas at the transmitter and receiver along with advanced digital signal processing to improve lin...

Antenna Diversity in Mobile Phone

In the new generation of mobile communication systems, high data transmission rate and low bit error probability have been common requirements. However the issue of signal fading in a multi-path environment still stands as an major problem. Using antenna diversity techniques can overcome the problem. The main purpose of this thesis work is to implement receiver antenna diversity in a mobile ter...
