messages used in the measurements consisted of a 40.2 kHz carrier wave, modulated by M-sequence pseudo random code of length 63 bits. The clock rate of the code was selected to be 1 kHz, which leads to a bandwidth of 2 kHz. The transmitted signal s(t) can be described as follow. s( t ) = p( t ). cos(0w ) (1) Where p(t) is the M-sequence pseudo random code and w o is the carrier frequency. Fig.3(a) indicates the generated M-sequence pseudo random code and Fig.3(b) indicates the power spectral density (PSD) of the transmitted signal. 110 PROCEEDINGS
