  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Proposal on Preamble Structure for IEEE 802.15.4b PHY] Date Submitted: [Nov 2004] Source: [Liang Li, Liang Zhang, Yafei Tian, Chenyang Yang, Zhijian Hu] Company: [WXZJ Inc./Helicomm Inc.] Address: [Building D, No.2, Shangdi XinXi Lu, Beijing, China 100085 ] Voice:[8610-13911895301], E-Mail:[liang_1@yahoo.com] Re: [ IEEE 802.15.4 ] Abstract: [This contribution proposes preamble structure for TG4 PHY layer.] Purpose: [To encourage discussion.] Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15. Liang Li, WXZJ Inc./Helicomm

  2. Outline This document proposes a preamble structure for 15.4b PHY, taking into account the possible needs for the operations of AGC, frame detection, time & frequency synchronization, and channel estimation, etc. Liang Li, WXZJ Inc./Helicomm

  3. Proposal for preamble Preamble of 15.4 standard: The preamble field proposed here consists of 6 octets. Preamble here proposed for 15.4b: Liang Li, WXZJ Inc./Helicomm

  4. Assumptions The proposed preamble structure is based upon the 15.4 experiences and the following assumptions & estimations: • O-QPSK modulation • Proposed E16 orthogonal code (4 bits/symbol) • 6 symbol time allocated for AGC operation (based on 15.4 receiver sensitivity & dynamic range) • Remaining 6 symbol time for operations of frame detection, synchronization, and channel estimation, etc. • The estimated time needed for each operation is relatively conservative, and some margin is included.
