Abstract: A serial concatenated coder includes an outer coder and an inner coder. The outer coder irregularly repeats bits in a data block according to a degree profile and scrambles the repeated bits. The scrambled and repeated bits are input to an inner coder, which has a rate substantially close to one.

Abstract: A turbo-like code is formed by repeating the signal, coding it, and interleaving it. A serial concatenated coder is formed of an inner coder and an outer coder separated by an interleaver. The outer coder is a coder which has rate greater than one e.g. a repetition coder. The interleaver rearranges the bits. An outer coder is a rate one coder.

Abstract: A wireless terminal includes an uplink rate option indicator in the same uplink channel segment with data, the rate option indicator providing transmission rate information about the data transmitted in the segment. The indicator value is represented by an energy pattern within the segment. Different energy patterns correspond to different indicator values. The number of indicator values is less than the number of possible uplink data rate options supported by the wireless terminal. A single indicator value represents different uplink data rate options, at different times, as a function of a received maximum data rate option and/or type of assignment message. The maximum data rate option and/or assignment message was transmitted by the same base station receiving the indicator value; therefore, there is no ambiguity between wireless terminal and base station as to the interpretation of the uplink data rate option indicator value with respect to an individual uplink segment.

Abstract translation: 无线终端包括与数据相同的上行链路信道段中的上行链路速率选项指示符，速率选项指示符提供关于在该段中发送的数据的传输速率信息。 指标值由段内的能量模式表示。 不同的能量模式对应于不同的指标值。 指标值的数量小于无线终端支持的可能的上行链路数据速率选项的数量。 单个指标值表示不同的上行链路数据速率选项，在不同的时间，作为接收到的最大数据速率选项和/或分配消息的类型的函数。 最大数据速率选项和/或分配消息由接收到指标值的同一基站发送; 因此，关于单个上行链路段的上行链路数据速率选项指示符值的解释，无线终端和基站之间没有歧义。

Abstract: A flexible and relatively hardware efficient LDPC decoder is described. The decoder can be implemented with a level of parallelism which is less than the full parallelism of the code structure used to control the decoding process. Each command of a relatively simple control code used to describe the code structure can be stored and executed multiple times to complete the decoding of a codeword. Different codeword lengths are supported using the same set of control code instructions but with the code being implemented a different number of times depending on the codeword length. The decoder can switch between decoding codewords of different lengths, without the need to change the stored code description information, by simply changing a code lifting factor that is indicative of codeword length and is used to control the decoding process. When decoding codewords shorter than the maximum supported codeword length some block storage locations may go unused.

Abstract translation: 描述了一种灵活且相对硬件有效的LDPC解码器。 该解码器可以用低于用于控制解码过程的代码结构的完全并行性的并行级别来实现。 用于描述代码结构的相对简单的控制代码的每个命令可以被多次存储和执行以完成码字的解码。 使用相同的一组控制码指令支持不同的码字长度，但是根据码字长度，代码被实现不同的次数。 解码器可以通过简单地改变表示码字长度的代码提升因子而不需要改变存储的代码描述信息来切换不同长度的解码码字，并用于控制解码过程。 当解码短于最大支持码字长度的码字时，一些块存储位置可能不被使用。
