| Summary: | A novel method based on clustered point process was proposed to calculate average bit error probability（ABEP） of UWB non-coherent system on IEEE 802.15.3a channel.In particular,the expectation and variance of the sig-nal to noise ratio（SNR） in the detection window were derived in closed form.Moreover,lognormal and normal variants were employed and compared to approximate the SNR in receiver window with respects to several characteristics.The results show that lognormal approximation is more feasible than normal approximation.In term of performance with PPM and OOK modulations,the efficiency of lognormal approximation is respectively much better than that of normal approximation. |
