  • Patent number: 10305631
    Abstract: A system for frame synchronization. Coarse synchronization is performed, in some embodiments, by using soft bit decisions to generate a list of candidate frame start positions, each with an associated estimated probability. The candidate frame start positions are then tested by decoding the frame data, and a frame start position for which a criterion of decoding success is met is selected. Fine synchronization is performed, in some embodiments, by using an encoded synchronization word in the encoded frame data. A first decoding pass is used to identify the position of the synchronization word. The start of the frame is inferred from the position of the synchronization word, and a second decoding pass, using the correct initial state, in the decoder, at the start of the encoded frame data, is performed.

  • Patent number: 10135585
    Abstract: In a transmitter, first and second sets of discrete multitone (DMT) sub-carrier signals or tones are identified. First and second bit groups of a payload data frame corresponding to the first and second sets of tones are selected. The first bit group is then trellis encoded. The second bit group is not trellis encoded. The first trellis coded tone group and the second bit group are then constellation mapped to produce a DMT symbol for transmission. A receiver may use an estimate of signal-to-noise ratio (SNR) of each tone to determine whether to select the tone for inclusion in the first or second set of tones. The receiver may provide the transmitter with information indicating whether a tone is included the first or second set of tones.

  • Patent number: 10097213
    Abstract: Methods and systems for decoding monitored communication signals using previously identified side information. Information, which is used for decoding a given frame and is provided to the decoder not via the main communication channel between a base station and a mobile station, is referred to herein as “side information.” The side information can also be viewed as extrinsic information that was derived during previous decoding operations. The monitoring system holds, for certain frames, a-priori information of one or more data values that are expected in these frames. Decoding using this a-priori information enables an Error Correcting Code decoder to successfully decode such frames, which would otherwise fail to decode.
