Efficient Hybrid Modulation with Phase-Directed Pulse Position Estimation for UWB-IR Systems

Abstract: This paper proposes an efficient hybrid modulation scheme for a mixed phase-shift keying and pulse-position modulation (PSK/PPM) for heterogeneous networks employing ultrawideband impulse radio (UWB-IR). The proposed scheme can support both coherent and noncoherent reception and is compatible with the IEEE 802.15.4a standard. Conventional hybrid modulation schemes for heterogeneous networks are generally constructed with a super-orthogonal coding (SOC) technique with which coherent receivers can get an additio… Show more

“…UWB enables the usage of various modulation types, including on-of keying (OOK) [1], pulse amplitude modulation (PAM) [2], bi-phase shift keying (BPSK) [3], pulse position modulation (PPM) [4], pulse interval modulation (PIM) [5] as well as different hybrid modulation schemes which improves system performances [6], [7]. According to system complexity constraints and performance requirements, different receiver types are developed, e.g.…”
