Abstract: In one embodiment, a device in a computer network establishes a reliable map that defines a set of packet criteria for which reliability is desired over an unreliable link to a peer device. In response to receiving a first packet from the peer device over the unreliable link, the device acknowledges the first packet to the peer device when the first packet matches the packet criteria of the reliable map. Also, in response to receiving a second packet destined via the peer device over the unreliable link, the device buffers the second packet when the second packet matches the packet criteria of the reliable map and retransmits the buffered second packet over the unreliable link to the peer device until acknowledged by the peer device.

Abstract: The present invention provides a method for enhancing reliability of information transmission by (a) establishing a matrix based on the length of bits of valid information in frame time slots; and creating a new matrix by presetting Error Correction Coding (ECC) for rows and columns of said matrix; (b) adopting the 1st Interleaving method to re-allocate bits which have been processed twice by using said ECC in said new matrix, to both ends of said frame time slots; and (c) adopting the 2nd Interleaving method to re-allocate the remaining bits in said new matrix to the middle of said frame time slots. After processed like this, the anti-interfering ability of the bits at both ends of TDMA frame time slot can be significantly enhanced, and the bit-error rate is decreased most, and all redundancy bits of Hamming codes can be arrayed at both ends of TDMA frame time slot.

In one embodiment, a method to process bits in a bit stream comprises scrambling the bit stream; separating the scrambled bit stream into a high priority bit stream with an order of high priority bits from left to right and a low priority bit stream with an order of low priority bits from left to right; rearranging the bits by embedding the high priority bits in the low priority bit stream while preserving the two orders, the rearranged bit stream including blocks of bits, each block including one or more high priority bits disposed left of corresponding one or more low priority bits to provide protection for the high priority bits against noise which is at least equal to protection for the low priority bits; and modulating the rearranged bit stream using Gray encoding method to produce an encoded bit stream.
