This paper investigates multiuser detection technology for time hopping (TH) ultra-wideband (UWB) systems to cancel the multiple access interference (MAI) from desired signal. To reduce MAI, three interference cancellation schemes are employed: successive interference cancellation (SIC), successive interference cancellation with the maximum ratio (SIC-MR) and iterative interference cancellation with...
This paper investigates detection mechanisms for time hopping pulse position modulated (TH-PPM) multiple access systems in both additive white Gaussian noise and fading environments. In such systems, the raw data is not linearly related to the received signal. One technique is to express the pulse position modulated signal as the sum of linearly modulated signals with the input being a nonlinear function...
