Abstract :
A broadband 26 GHz WLL test platform using a transposition of a DCS 1800 link is validated in this paper. For this validation, 26GHz RF signal is modulated by a pseudonoise sequence with a quadrature phase shift keying modulation is used. The receiver performance is studied in which the binary sequence is regenerated, and after frame synchronization thus the comparison between regenerated data and that used for the demodulation, bit error rate (BER) is found. The interferences between the transmission links and propagation channel effects are also studied.
