    Design of a Control Logic in a Dynamic Reconfigurable System

    this paper, the authors propose an architecture for controlling Dynamic Reconfigurable systems. The processor instructions when compiled one by one produces very high delay overhead. If these instructions are converted into a combinational logic then the overhead can be reduced thereby making the system an efficient one. This paper presents...

    Study of ICI Cancellation Techniques in OFDM

    OFDM (Orthogonal Frequency Division Multiplexing) is a well known technique in 4G Broadband wireless communication systems. OFDM has high spectral efficiency but it suffers from frequency offset problem due to the difference between transmitter and receiver local oscillator frequencies which causes loss of orthogonality between subcarriers leading to ICI. This...
