    Abstract: The commercial formulation of fast dispersing dosage forms (FDDF) requires substantial holding times during which large quantities of pharmaceutically active substance are formed into individual dosage units. During this holding time, pharmaceutical agents with a propensity to polymorphism in an aqueous environment may crystallize into various, and sometimes unpredictable forms. These crystalline forms may affect the efficacy of the pharmaceutical agent. Previous attempts to control this process have included attempts to direct crystallization into a stable form. The instant invention acts to suppress crystallization, by utilizing a combination of standard molecular weight fish gelatin and a low processing temperature, to suppress crystallization to a degree that is not accomplished by either the use of standard molecular weight fish gelatin or low processing temperatures individually.

    Abstract translation: 快速分散剂型（FDDF）的商业制剂需要大量的保持时间，在此期间大量的药物活性物质形成单个剂量单位。 在此期间，具有在含水环境中多晶型倾向的药剂可能会结晶成各种不同的，有时不可预测的形式。 这些结晶形式可能影响药剂的功效。 先前控制该过程的尝试包括尝试将结晶引导至稳定形式。 本发明通过利用标准分子量鱼明胶和低加工温度的组合来抑制结晶，以将结晶抑制到通过使用标准分子量鱼明胶或单独的低加工温度所不能达到的程度。

    Abstract: A wireless communication system (10), an encoding method (300) for encoding a binary input signal and a decoding method (800) for decoding a coded baseband signal within the wireless communication system (10) are described. The system (10) has an encoding section (12) and a decoding section (14). The encoding section (12) has a mapper (26) for mapping bits into symbols, and an encoder (28), coupled to the mapper (26), for encoding the symbols to corresponding integers modulo M, where M is an arbitrary predetermined integer. Coded symbols are derived from the corresponding integers. At the decoding section (14), a decoder (40) decodes an output phasor stream of a coded baseband signal to derive an estimate of a codeword. Thereafter, a demapper (42) demaps the estimate of the codeword to derive the bits from decoded symbols.
