摘要： The present application describes a method and filter for shaping a series of pulses spaced in time for subsequent transmission in a communications system, each of the pulses having a magnitude comprising the steps of providing a generic shaped pulse, for each pulse in the series, generating a shaped pulse by scaling the generic shaped pulse by an amount proportional to the magnitude, wherein at least a portion of each generated pulse overlaps in time with at least a portion of at least one subsequent generated pulse, and combining the overlapping portions of the generated pulses. The present application also describes a method and apparatus for modulating an input signal comprised of an ordered series of samples separated by a substantially constant period T comprising the steps of providing a carrier signal, the carrier signal comprised of a series of samples separated by a substantially constant period T, wherein one of the carrier samples corresponds to each of the input signal samples, selecting a plurality of N successive samples from the series of input signal samples, the series of samples having an input order, for each of the N selected samples in parallel, multiplying the selected sample by the corresponding carrier sample and recombining the N multiplied samples while maintaining the input order.
摘要翻译：本申请描述了一种用于对一系列脉冲进行整形以在随后的通信系统中传输的脉冲的方法和滤波器，每个脉冲具有幅度，包括为串联中的每个脉冲提供通用成形脉冲的步骤，通过将通用成形脉冲缩放与幅度成比例的量的成形脉冲，其中每个产生的脉冲的至少一部分在时间上与至少一个后续产生的脉冲的至少一部分重叠，并且将所产生的脉冲的重叠部分脉冲。本申请还描述了一种用于调制包括由基本上恒定的周期T分离的有序序列的输入信号的方法和装置，包括以下步骤：提供载波信号，载波信号由一系列采样分离的样本恒定周期T，其中载波样本中的一个对应于每个输入信号样本，从所述一系列输入信号样本中选择多个N个连续样本，对于所选N个样本中的每一个，所述一系列样本具有输入阶数并行地，将所选择的样本乘以相应的载波样本，并重新组合N个相乘的样本，同时保持输入顺序。
