Abstract
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.
Claims18
A method of operating a physical layer (PHY) of a body area network (BAN) device, the method comprising:
- generating a physical-layer convergence protocol (PLCP) preamble, including concatenating a 63-bit m-sequence with a 27-bit extension sequence including bit values of 010101010101101101101101101;
- generating a PLCP header;
- transforming a physical-layer service data unit (PSDU) into a physical-layer protocol data unit (PPDU) pre-appended with the PLCP preamble and the PLCP header;
- and
- transmitting the PPDU at a data rate based on an operation frequency band.
