Reduced-size ultra-wideband true-time-delay beam-forming receivers Conference Paper uri icon

abstract

  • This paper presents two novel ultra-wideband (UWB) true-time-delay beam-forming receiver architectures to reduce the size of the receiver compared to the reported beam-forming receivers. Size reduction is due to lowering the total amount of delay by half and employing a negative feedback loop in the receiver. The proposed systems are analyzed to investigate their response, Inter-symbol-Interference (ISI) rejection, stability, beam width, signal to noise ratio (SNR) and the effect of non-idealities. The simulation results prove that the first proposed system has lower area for the same number of antennas and half the delay compared to the existing receivers at the cost of lower SNR and wider beam width. The second system results in a smaller size and better SNR for half the delay compared to the existing receivers at the cost of higher complexity. 2011 IEEE.
