摘要： Techniques for puncturing symbols in a communications system. S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. A number of puncture distances, D1 through DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. P1 through PN symbol punctures are then performed at the distances of D1 through DN, respectively. For a more even distribution of the symbol punctures, each of the distances D1 through DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as D min = └ S / P ┘, where L ┘ denotes a floor operator. The symbol punctures at each computed distance can be performed together or distributed with symbol punctures at other distances.

摘要翻译： 在通信系统中穿孔符号的技术。 对于具有N个符号的容量的帧接收S个符号，其中S大于N.P个符号需要被穿孔，使得剩余的符号适合于帧。 基于S和P计算多个穿刺距离D1至DN。针对每个计算的穿刺距离确定特定数量的符号穿孔。 然后分别在D1到DN的距离处执行P1到PN符号穿孔。 为了更均匀地分配符号穿孔，可以将距离D1至DN中的每一个选择为大于或等于定义为D min =“”S / P“的最小穿孔距离Dmin，其中L”〜 一个地板操作员。 在每个计算距离处的符号穿孔可以一起执行或者以其他距离的符号穿孔分布。

摘要： A method is taught for improving the transmission of information signals in a communications system having a base station and a remote station. First and second transmission links are established with the remote station. An information signal is encoded to provide an encoded information signal having more bits than the information signal. First and second transmission signals are provided wherein each transmission signal has bits selected from the encoded information signal. Each of the first and second transmission signals is transmitted to the remote station by way of a respective one of the first and second transmission links. The remote station receives and combines the first and second transmission signals transmitted by the remote station to provide a combined encoded signal. The combined encoded signal is decoded by the remote station to provide the information signal. The first and second transmission links can be formed between the remote station and a single base station or between the remote station and two separate base stations.
