  • Patent number: 9973300
    Abstract: Systems, methods, and apparatuses are disclosed for choosing the modulation mode using packets transmitted by a sender to a receiver, wherein the packets contain data patterns unknown to the receiver. In some embodiments, the sender sends of a data packet in the most robust mode available, such that the packet can be correctly received by the receiver under even the noisiest conditions. The data contained in the packet is demodulated and decoded. A cyclic redundancy check is performed to ensure that the resultant data is error-free. Once the transmitted payload data is known, the original error coding can be re-applied to the payload data to produce the transmitted bit stream. Comparison of the demodulated bit stream to the regenerated transmitted bit stream yields the pattern of errors. The pattern of errors is analyzed and a higher throughput decoding scheme is chosen based on the results of the analysis.
