erformance of DH-PIM Employing Equalisa

Introduction e demand for mobile connectivity and the need for high reless (interactive) multimedia are some of the reasons fo ) wireless communications. IR communications have im quest of present day bandwidth hungry applications. jects, i.e. no interference from other light sources in the velength in the adjacent rooms, building etc [1-4]. The u IR wireless communication only prevents multipath fadin opagation constitute a major system impairment espec ximum likelihood sequence detection (MLSD) technique lay may be prohibitive in many applications [5]. Therefore ployed to combat the effect of ISI due to multipath propag -PIM offers good characteristics for IR wireless syste atively straightforward slot synchronisation, higher bit rat offers improved immunity to multipath dispersion at high wer and higher probability of slot errors compared w rformance of unequalised DH-PIM is well documented in -PIM employing equalisation. In this paper we analyse a E equaliser and Monte Carlos simulation and compare re IM. In DH-PIM symbols, the guard band after the pulse c α and L; 2 and 8 are used for α and L respectively thr annel model and its characteristics. Section 3 gives the s e conclusions of the paper are in section 5.
