Probability of Slot-States in PPM-CDMA transmission over a diffuse channel
Trinh The Huynh, Takeshi Hashimoto (UEC)
Abstract (in Japanese) (See Japanese page) 
(in English) In pulse position modulation(PPM) CDMA over a diffuse link, the time-dispersion in the channel receivered waveform causes strong intersymbol interference(ISI) and make theoretical analysis difficult.
In this report, we derive a general formula for slot-states probabilities,which enable us to compute the bit error rate(BER) in a simpler fashion. Moreover, we use this formula to analyze the performance of our system by taking the self interference caused desired codeword into consideration, which allow more accurate analysis than the previous report.
