Robust Beamforming for GNSS Synthetic Antenna Arrays
The impetus for this paper and the underlying research is to investigate and develop robust beamforming algorithms with synthetic antenna arrays for GNSS signals. The concepts of synthetic array based beamforming and Angle-Of-Arrival (AOA) estimation for Global Navigation Systems (GNSS) signals are described in this paper. The core idea is the utilization of GNSS antenna motion to synthesize a ...
متن کاملCapacity Enhancement of Ad Hoc Networks using a New Beamforming Scheme Based on ESPAR
This paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (ESPAR). The proposed method is capable of providing better capacity compared to the conventional ESPAR. The termination of each antenna element in this structure comprises a PIN diode in addition to a varactor. Using PIN diode besides the varactor provides more degrees of freed...
متن کاملبررسی تأثیر فاصلهی بین آنتنها در فرستنده و گیرنده بر روی ظرفیت کانال MIMO
In this paper, the spatial MIMO channel modeling (SCM) is introduced and the required parameters for this modeling are studied. Then, the MIMO channel gains and capacity are analyzed. The transmitter and receiver antenna patterns are also analyzed. Next, we are focused on the effects of the transmitter and receiver antenna arrays separations, the arrays length, and the angles spread on the ante...
متن کاملA Real Time Downlink Channel Allocation Scheme for an Sdma Mobile Radio System
In SDMA mobile radio systems where only base stations, but no mobiles are equipped with antenna arrays, co-channel interference on the downlink has to be kept down by beamforming. The performance of the beamformer is determined by the directions of arrival (DOAs) of the users operating in the same frequency/tixne/code slot. Thus the full capacity of an SDMA cell can only be made use of by an ef...
متن کاملAdaptive interference suppression in multiuser wireless OFDM systems using antenna arrays
This paper considers the problem of mitigating fading and interference in wireless orthogonal frequency division multiplexing (OFDM) multiple access communication systems. Applications include cellular mobile radio, wireless local loop, and wireless local area networks. The effect of interchannel interference (ICI) arising from time-selective fading and frequency offsets and co-channel interfer...
