PHY layer options for body area network (BAN) devices

摘要

In at least some embodiments, a communication device includes a transceiver with a physical (PHY) layer. The PHY layer is configured for body area network (BAN) operations in a limited multipath environment using M-ary PSK, differential M-ary PSK or rotated differential M-ary PSK. Also, the PHY layer uses a constant symbol rate for BAN packet transmissions.

1. A physical (PHY) layer method, comprising:
performing body area network (BAN) operations in a limited multipath environment using M-ary PSK, differential M-ary PSK or rotated differential M-ary PSK, wherein performing BAN operations comprises preparing a BAN packet for transmission, the BAN packet comprising a physical-layer protocol data unit (PPDU) having a physical-layer convergence protocol (PLCP) preamble, a PLCP header, and a physical-layer service data unit (PSDU), preparing the PLCP preamble with an m-sequence and an extension sequence having a timing sequence followed by a DC-balanced sequence; and transmitting BAN packets at a constant symbol rate.
