متن کاملAll-digital impulse radio with multiuser detection for wireless cellular systems
Impulse radio is an ultrawideband system with attractive features for baseband asynchronous multiple-access, multimedia services, and tactical wireless communications. Implemented with analog components, the continuous-time impulse radio multiple-access model utilizes pulse-position modulation and random time-hopping codes to alleviate multipath effects and suppress multiuser interference. We i...
متن کاملPerformance of ultrawideband SSMA using time hopping and M-ary PPM
Wireless spread spectrum multiple access (SSMA) using time hopping and block waveform encoded ( -ary) pulse position modulated (PPM) signals is analyzed. For different -ary PPM signal designs, the multiple-access performance in free-space propagation conditions is analyzed in terms of the number of users supported by the system for a given bit error rate, signal-to-noise ratio, bit transmission...
متن کاملPerformance analysis of time-hopping spread-spectrum multiple-access systems: uncoded and coded schemes
In [Scholtz (1993)], an ultra-wide bandwidth time-hopping spread-spectrum code division multiple-access system employing a binary PPM signaling has been introduced, and its performance was obtained based on a Gaussian distribution assumption for the multiple-access interference. In this paper, we begin first by proposing to use a practical low-rate error correcting code in the system without an...
