    Abstract: A network coding system. A packet decoding engine receives a number of received packets. A packet repository is coupled to the decoding engine to temporarily store the received packets. The packet decoding engine is configured to generate a decoding matrix by forming a sub-matrix by selecting columns of a network code matrix that have indices that are the same as the indices of the encoded packets that correspond to the selected received packets. The packet decoding engine is also configured to invert the sub-matrix to form the decoding matrix and multiply the received packet matrix by the decoding matrix to generate a recovered matrix where each column corresponds to a decoded packet.

    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 based on a constant symbol rate for BAN packet transmissions and based on M-ary PSK, differential M-ary PSK or rotated differential M-ary PSK modulation. The PHY layer is configured to transmit and receive data in a frequency band selected from the group consisting of: 402-405 MHz, 420-450 MHz, 863-870 MHz, 902-928 MHz, 950-956 MHz, 2360-2400 MHz, and 2400-2483.5 MHz.

    Abstract: A symbol modulation system applicable to a body area network is disclosed herein. The symbol modulation system includes a symbol mapper. The symbol mapper is configured to determine a time within a predetermined symbol transmission interval at which a transmission representative of the symbol will occur. The time is determined based on a value of a symbol and a value of a time-hopping sequence. The time is selected from a plurality of symbol value based time slots, and a plurality of time-hopping sequence sub-time-slots within each symbol value based time slot. The symbol mapper is configured to generate a single guard interval within the symbol transmission interval. The single guard interval is positioned to terminate the symbol transmission interval.
