The demodulator includes an A/D converter for converting the input signal in digital form, in which, for the A/D converter sampling, a sampling number M of every symbol interval satisfies an equation M.gtoreq.2K+1, wherein K is the interval number of a carrier of the input signal in each symbol interval. N filter arrays each respectively receive the input signals in digital form, and each one of the N filter arrays has a filtering frequency band, respectively, corresponding to spectrums of N symbols in N-ary FSK modulation. N downsamplers each receive the input signal from the corresponding filter array and reduce the sampling number of the input signal to make each symbol interval include only one sample value. N absolute-value generators each receive the input signal from the corresponding downsampler and calculate the absolute value of the sample value of the input signal. A maximum detector receives the outputs of the absolute value generators and detects the maximum in the outputs to decide the symbols represented by each symbol interval, so as to output data.

摘要： In a wireless infrared communications system, a technique for encoding data for serial transmission and the correlative technique for decoding the transmitted data. A data transmission period is divided into a plurality of slots. In a given pair of slots, the first slot comprises a gray code sequence of bits and a check bit, and the second slot comprises the same gray code sequence of bits and the complement of the check bit in the first slot. The last slot in a transmission time period comprises a guard slot to separate transmission time periods. A decoder receives the encoded data, and for a given slot derives calculated data for the slot from the gray code sequence of bits and the check bit. The check bit for the given slot is compared with a calculated check bit of the previous slot to determine if a predetermined relationship exists. If the predetermined relationship exists, the received encoded data is selected as the output of the decoder, and if the predetermined relationship does not exist, the calculated data is selected as the output of the decoder. The calculated check bit is derived from the output of the decoder for a slot, and is compared with the check bit of the encoded data for the following slot.

摘要： A method for an end-to-end hybrid automatic repeat request and a system thereof are provided. The method is applicable in a cognitive radio network (CRN) including at least a source node and a destination node. There are paths between a source node and a destination node in the CRN, and each path has a plurality of wireless links. The method includes the following steps. The source node encodes information into a coded packet, divides the coded packet into coded sub-packets, and transmits the coded sub-packets to the paths. Through the wireless links of each path, a coded sub-packet is amplified and forwarded to the destination node. In addition, the destination node combines the coded sub-packets for decoding so as to recover the information, and transmits an acknowledgement packet to the source node for notifying whether the information is successfully recovered.
