    • A method for correlation of an input signal in a receiver is disclosed as well as a receiver and a communication system for implementing the method. The input signal is correlated with Generalized Chirp-Like (GCL) sequences being derived from a single Zadoff-Chu sequence modulated with at least two modulation sequences. The method includes at least the steps of processing samples of the input signal in a first delay line, in a Discrete Fourier Transform (DFT) circuit and in a second delay line. According to the invention, a multiplication of samples of the input signal with elements of modulation sequences corresponding to the at least two modulation sequences being used for deriving the GCL sequences is performed in a step after the processing in the first delay line. Then a DFT processing is performed using a DFT circuit.

    • A transmitter in which modulator output signal values are generated by a multi-level modulation method. The transmitter comprises a look-up table for storing a pre-defined number of values corresponding to data symbols and representing a signal or a pulse format, registers for selecting values representing the signal or the pulse format to be used to defined in-phase and quadrature component values, and adders for defining the modulator output signal values by summing the in-phase and quadrature component values while the number of the in-phase and quadrature component values to be summed is determined by a number of inter-dependent symbols.

    • A method in a base station for detecting a HARQ-ACK codeword comprised in a signal received from a UE is provided. The base station knows HARQ-ACK codewords being possible to detect. The base station receives (401) a signal from the UE comprising a modulation symbol. The base station estimates (402) a SNR value for the received signal, and calculates (403) soft values for the modulation symbol. When the SNR value is lower than a predetermined threshold value and when the modulation symbol of the received signal comprises more than two bits per modulation symbol, the base station uses a first mode. The first mode comprises correlating (405) only the two first calculated soft values for the modulation symbol with the one or more known possible HARQ-ACK codewords. In other cases, i.e. when the first mode is not used, the base station uses a second mode. The second mode comprises correlating (408) all calculated soft values for the modulation symbol with the known possible HARQ-ACK codewords.
    • 提供了一种用于检测包括在从UE接收的信号中的HARQ-ACK码字的基站中的方法。 基站知道可以检测的HARQ-ACK码字。 基站接收(401)包括调制符号的来自UE的信号。 基站估计(402)接收信号的SNR值,并计算(403)调制符号的软值。 当SNR值低于预定阈值时,并且当接收信号的调制符号包括每个调制符号多于两个比特时,基站使用第一模式。 第一模式包括(405)仅将调制符号的两个第一计算的软值与一个或多个已知的可能的HARQ-ACK码字相关联。 在其他情况下,即当不使用第一模式时,基站使用第二模式。 第二模式包括将调制符号的所有计算的软值与已知的可能的HARQ-ACK码字相关联(408)。

    • A basic idea is to determine (S1) occurrence of a glitch caused by operation of the AGC mechanism, identify (S2) those modulation symbols in a digitized version of the received signal that are affected by the glitch, each modulation symbol represented by a number of bits in combination, and then reduce (S3), for each of the identified modulation symbols, the contribution in representing the identified modulation symbol as provided by at least a subset of the bits of the modulation symbol. In this way, the adverse effects of the glitch can be effectively mitigated and subsequent detection of the desired signal can be significantly improved. This also means that the link performance will be significantly improved.
    • 一个基本思想是确定(S1)由AGC机构的操作引起的毛刺的发生,识别(S2)受毛刺影响的接收信号的数字化版本中的那些调制符号,每个调制符号由数字 的比特,然后对于每个所识别的调制符号,减少(S3)表示由调制符号的比特的至少一个子集提供的所识别的调制符号的贡献。 以这种方式,可以有效地减轻毛刺的不利影响,并且可以显着地提高对期望信号的后续检测。 这也意味着链路性能将显着提高。
