摘要： A transmitting node is configured to transmit a sequence of information bits using a serially concatenated coding system (72). The transmitting node (18) in this regard outer encodes information bits (28) in the sequence by encoding any given information bit independently of any other information bits in the sequence. The transmitting node (18) interleaves the outer coded bits (76) using a recursively addressed interleaver (80). Interleaving thereby includes computing any given output address of the interleaver (80) from one or more previously computed output addresses. The transmitting node (18) also digitally modulates the interleaved bits (82) in order to generate modulation symbols (34). Digitally modulating the interleaved bits (82) entails generating a modulated symbol for a current symbol period in dependence on a modulated symbol for a previous symbol period.
摘要翻译：发送节点被配置为使用串行级联编码系统（72）发送信息比特序列。在这一点上，发送节点（18）通过对序列中的任何其他信息比特独立地编码任何给定信息比特来对序列中的信息比特（28）进行外部编码。发射节点（18）使用递归寻址的交织器（80）来交织外部编码比特（76）。因此，交织包括从一个或多个先前计算的输出地址计算交织器（80）的任何给定的输出地址。发射节点（18）还对交织比特（82）进行数字调制，以产生调制符号（34）。对交织比特（82）进行数字调制需要根据先前符号周期的调制符号为当前符号周期生成调制符号。

摘要： A system, method and node for unambiguous encoding of Physical Downlink Control Channel (PDCCH) channels in a Long Term Evolution (LTE) telecommunications system to remove detection errors. The method includes modifying a size of a circular buffer where the coded bits are collected to avoid repetition of the coded bits in consecutive subset of the control channel elements allocated to the PDCCH. The size of the circular buffer is selected so that it is not equal to the number of coded bits output from the encoder. Coded bits can be deleted from or added to the coded bit sequence depending on the size of the circular buffer.
