Bpsk power spectral density
WebThe noise power density, N 0 =kT, is the receiver noise power per hertz, which can be written in terms of the Boltzmann constant k (in joules per kelvin) and the noise temperature T (in kelvins).

Webbandwidths, where the energy per bit to noise power spectral density ratio is E b=N 0 and the spreading factor is SF. Eq. 3 is used in the remainder of this paper for the BER of CSS. The equation shows that for higher spreading factor the BER curve is steeper. Fig. 1 also shows the performance of a BPSK symbol (Eq. 2) [11]. Fig. 1 shows that ...
