    • Quadratic polynomial permutation (QPP) interleaver providing hardware saving and flexible granularity adaptable to any possible turbo code block size. A means is presented by which only a very small number of coefficients need be stored to effectuate a wide variety of QPP interleaves as can be employed in the context of turbo coding. In one instance, to accommodate the approximate 6000 different turbo code block sizes in 3GPP LTE channel coding, only 5 different coefficient values need to be stored to effectuate a very broad range of QPP interleaves to be applied each of those various turbo code block sizes. Moreover, a few small number of dummy bits, if any, need to be employed to accommodate a very broad range of turbo code block sizes. It is noted that the QPP interleaving as described herein can be applied to turbo encoding and turbo decoding (e.g., including both interleaving and de-interleaving).
    • 二次多项式置换(QPP)交织器,提供适用于任何可能的turbo码块大小的硬件保存和灵活的粒度。 提出了一种手段,其中仅需要非常少量的系数来存储多个QPP交织以便在turbo编码的上下文中使用。 在一种情况下,为了适应3GPP LTE信道编码中的大约6000个不同的Turbo码块大小,仅需要存储5个不同的系数值,以实现要应用那些各种turbo码块大小中的每一个的非常宽范围的QPP交织。 此外,需要采用少量的虚拟位(如果有的话)以适应非常宽范围的turbo码块大小。 注意,如本文所述的QPP交织可以应用于turbo编码和turbo解码(例如,包括交织和解交织两者)。

    • A method of decoding a signal that has been encoded by a tail-biting code based on at least one encoding parameter is disclosed. The at least one encoding parameter may be a trellis size or a quantity of aggregated encoding elements or a code rate. The method is suitable for use in a communication device and comprises receiving (510) the signal, performing (520) a first decoding attempt of the signal based on a first set of starting state metrics and a first encoding parameter hypothesis, the first decoding attempt resulting in a first set of ending state metrics. The method further comprises performing (520), if the first decoding attempt fails, a second decoding attempt of the signal based on a second set of starting state metrics based on the first set of ending state metrics and a second encoding parameter hypothesis different from the first encoding parameter hypothesis. Corresponding arrangement, communication device, and computer program product are also disclosed.

    • Provided is a mobile station which can obtain an equivalent diversity effect in each communication scheme while keeping to an minimum the increase in the circuit scale of a mobile station even when the mobile station is compatible with a plurality of communication schemes. In a mobile station (100) which performs either single-carrier frequency-division multiple access (SC-FDMA) communication or orthogonal frequency division multiple access (OFDMA) communication, an interleaving unit (103) interleaves a plurality of resource elements, which are divided into a plurality of code blocks, in a plurality of code blocks when either SC-FDMA or OFDMA communication is performed. In addition, only when OFDMA communication is performed, a serial-to-parallel (SIP) converter (107) converts the data symbols to parallel streams and generates the OFDM symbols. A shifter (108) provides a different frequency shift to each OFDM symbol for the OFDM symbols input from the S/P converter (107), and distributes and places the plurality of resource elements of each plurality of code blocks after interleaving in the frequency domain.
