    摘要: A non-coherent frequency shift keying (FSK) demodulator, for receiving a N-ary FSK modulated input signal, demodulating the signal to obtain output data, in which the N-ary FSK modulation has N symbols, and the output data is constructed by a plurality of symbol intervals. 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: 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.
