On the above equation, z[n] is the AWGN noise with single-sided noise spectral density [N.sub.0] which is added in one complete OFDM frame, and [x.sup.diff] [n] is the bipolar signal which is exactly equal to the 1st half of [x.sup.s1] [n].

Therefore, the average transmitted electrical power [P.sub.l] of the bipolar signal at the 1th stratum is given by

Figure 3(a) shows a bipolar signal from an EHG register taken during the early stages of labor; the other three bipolar signals are not shown due to space issues.

The generated bipolar signal, [x.sub.n], is then converted to unipolar through clipping of all negative values at zero before modulating the LED.
