摘要： The modulation method and system of the presented herein involves mapping data onto a constellations comprising a set of concentric circles in a two-dimensional plane, one dimension for the amplitude and one for the phase. The phase dimension is coded differentially, while the amplitude dimension is coded coherently. The circles in each constellation may contain equal number of points, and in other embodiments more points may be used on the outer circles. The data may be coded with dual Trellis codes, one code for the phase data and another code for the amplitude data.

摘要： Methods and systems of low density parity check coded (LDPCC) coding are disclosed herein in which a set of LDPC codes ensure reliable transmission for channels in which modulation symbols may undergo attenuation in a random fashion. Methods and systems of LDPC coding disclosed herein include choosing a code blocklength and concatenating codewords into which a data packet can be encoded. To optimize the coding scheme, first, codeword shortening is performed to ensure an integer number of codewords for a desired packet length. The codewords may then be punctured or repeated to ensure an integer number of channel symbols per codeword. Shortening and puncturing repetition methods are implemented to yield minimum overhead while keeping the effective coding rate low.
摘要翻译： 本文公开了低密度奇偶校验编码（LDPCC）编码的方法和系统，其中一组LDPC码确保了调制符号可以以随机方式经历衰减的信道的可靠传输。 本文公开的LDPC编码的方法和系统包括选择代码块长度和级联码字，其中可以编码数据分组。 为了优化编码方案，首先，执行码字缩短以确保所需分组长度的整数个码字。 然后可以对码字进行删截或重复，以确保每个码字的整数个信道符号。 实现缩短和删截重复方法以产生最小开销，同时保持有效编码率低。

摘要： A method of decoding channel outputs using an iterative decoder to provide hard decisions on information bits includes activating each SISO decoder of the iterative decoder to provide soft-decisions associated with the information bits. The method also includes computing a fidelity estimate and stopping decoding based on the fidelity estimate.

摘要： The disclosure proposes bit-error-rate (BER) and symbol-error-rate (SER) estimation techniques and its application to incremental-redundancy and rate-adaptation for modern-coded hybrid-ARQ systems. In particular, BER/SER estimators are proposed based on iterative refinement of mixture-density modeling of the bit/symbol decision metrics. For hybrid-ARQ systems, rate-adaptation functions are proposed based on BER/SER estimators for failed transmissions. Methods are disclosed for code-rate selection based on successfully decoded blocks as well as incremental parity size selection for retransmission of failed blocks Techniques disclosed here apply to forward-error-correction codes employed for digital data communication systems.
