Third generation mobile communication systems based on the WCDMA air interface employ RAKE reception. Increasing the number of Rake fingers, helps to capture more multipath energy but at the expense of increased receiver complexity. Mobile radio channel measurements at 1945 MHz and 2135 MHz were carried out in Manchester city centre. Statistics of relative power and excess delay of multipath components...
All Orthogonal frequency division multiplexing OFDM, simulators that have been built so far employ a finite impulse response (FIR) tapped delay line filter. A channel simulator for OFDM can also be constructed in the frequency domain using FFT convolution. This paper presents the SIMULINK implementation of a frequency domain channel simulator for OFDM based physical (PHY) layer of Broadband wireless...
Two radio channel simulators based on the time variant frequency transfer function have been implemented using digital signal processing techniques in SIMULINK. The first simulator uses a two ray channel model to determine the number of taps per coherent bandwidth of the channel by comparing the bit error rate (BER) with the tapped delay line model for differential quadrature phase shift keying. The...
