摘要： Techniques for decoding repeated messages sent from a transmitter are improved with information obtained from the decoding of the first transmission and by augmenting Chase combining techniques with a voting-based combining method. In an example method, first encoded bits corresponding to a first instance of the repeated message and demodulated to obtain first soft bits, which are decoded to obtain first decoded bits. Second encoded bits corresponding to a second instance of the repeated message are demodulated to obtain second soft bits. The first decoded bits are re-encoded to obtain re-encoded bits. Sign values for modified soft bits are determined from sign values for the first soft bits, the sign values for the second soft bits, and the sign values for the re-encoded bits. The modified soft bits are combined with the first soft bits and decoded.

摘要： Example implementations relating to converting binary data, representative of either an executable code or a media file, into images are described. For example, techniques for converting the binary data include performing error detection encoding on the binary data to obtain encoded binary data and clustering the encoded binary data into multiple tuples, each tuple comprising 'n' number of bits, where 'n' is an integer. Thereafter, the 'n' number of bits of a tuple are segmented by an integer 'x' to obtain multiple bit sequence comprising 'n/x' number of bits, where 'n' is multiple of 'x' and each bit sequence is associated with a distinct colour. An image comprising 'x' number of sectors is then generated. Each sector corresponds to a bit sequence and includes a colour corresponding to the bit sequence. Thereafter, the image is printed on a printable medium.

摘要： A high-sensitivity receiver may be made by using multiple demodulators to demodulate a given signal. For example, the receiver may use a first demodulator to demodulate an input signal into a first sequence of soft bits and a second demodulator to demodulate the same input signal into a second sequence of soft bits. The two sequences of soft bits may then be compared and combined to create a sequence of hard bits. For example, in some embodiments, a soft bit combiner may combine the two sequences of soft bits into a third sequence of soft bits, which may then be input into a decoder to produce the final decoded hard bits. The secondary demodulator may be less complex, less expensive, demand less power, and/or require fewer computational resources when operating, than the first demodulator.
摘要翻译：高灵敏度接收器可以通过使用多个解调器来解调给定信号来制造。例如，接收机可以使用第一解调器将输入信号解调为第一软比特序列，第二解调器将相同的输入信号解调为第二软比特序列。两个软比特序列然后可以被比较和组合以产生硬比特序列。例如，在一些实施例中，软比特组合器可以将两个软比特序列组合成软比特的第三序列，然后可以将其输入到解码器中以产生最终的解码硬比特。与第一解调器相比，次级解调器可以更简单，更便宜，需要更少的功率，和/或在操作时需要更少的计算资源。

摘要： A wireless communication system delays serviced data communications to produce a desired level of voice communications capacity. The system first determines whether the wirless communications system has sufficient voice communications capacity. If it is determined that the wireless communication system has insufficient voice communication capacity, the system determines a data communications delay that is required to provide sufficient voice communications capacity. Based upon its determination, the system then selectively delays some or all of the data communications to create the sufficient voice communications capacity. In one operation, one data communications (116) serviced by the wireless communication system is selectively delayed to create the sufficient voice communications capacity. In another operation, a plurality of data communications (116, 122, 130, 128, and 132) serviced by the wireless communication system are selectively delayed to create the sufficient voice communications capacity. When a plurality of data communications are being serviced by the wireless communication system, some of the plurality of the data communications are delayed by a first delay level and other of the data communications serviced are delayed by a second delay level.
