Abstract :
The spectral signature of IEEE 802.11b 11 Mbps complementary code keying (CCK) wireless fidelity (Wi-Fi) signals is identified through an exact derivation of its power spectral density (PSD). This theoretical result was verified by computer simulation. The spectral signature of the 11 Mbps CCK-spread signal is compared with that of the 5.5 Mbps CCK-spread signal, as well as the Barker-spread signals. The adjacent channel interference power and interference temperature caused by different Wi-Fi interferers are calculated and presented
