摘要： Methods and arrangements are provided where signalling of the modulation type by means of rotation of the training sequence is provided. For each modulation type, a set of rotation angles is chosen. These sets have no element in common. New training sequences are generated by rotating one original training sequence. The rotation angle that minimizes the PAPR of the transmit signal can be chosen. At the receiver side, knowing the original training sequence, the receiver estimates blindly the rotation angle among the known possible rotation angles. The estimated rotation angle in the receiver maps to a unique modulation type.

摘要： Techniques for decoding repeated messages sent from a transmitter are improved with information obtained from the decoding of the first transmission and by augmenting Chase combining techniques with a voting-based combining method. In an example method, first encoded bits corresponding to a first instance of the repeated message and demodulated to obtain first soft bits, which are decoded to obtain first decoded bits. Second encoded bits corresponding to a second instance of the repeated message are demodulated to obtain second soft bits. The first decoded bits are re-encoded to obtain re-encoded bits. Sign values for modified soft bits are determined from sign values for the first soft bits, the sign values for the second soft bits, and the sign values for the re-encoded bits. The modified soft bits are combined with the first soft bits and decoded.

摘要： Methods and devices for transmitting a burst of signals in a cellular radio system supporting data transmission using EGPRS/EGPRS2 are provided. The transmission involves providing additional symbols in the EGPRS/EGPRS2 burst thereby forming a long burst and pulse shaping the long burst to form a long baseband signal whose duration exceeds the duration of one EGPRS/EGPRS2 time slot. The long baseband signal is then shortened to a shortened burst having the duration of an EGPRS/EGPRS2 time slot wherein the shortened burst fulfills the same spectrum mask requirement as the EGPRS/EGPRS2 burst, which can be transmitted.

摘要： Data signals transmitted by a plurality of transmitting antennas over a radio channel are demodulated. The method comprises receiving (202) on a plurality of receiving antennas, a data signal and a reference signal, the contents of the reference signal being known a priori to the receiver. The contents of the reference signal are used for calculating (204) an estimated polynomial channel matrix. A polynomial pre-filter matrix is calculated (206, 208) by a decomposition of the estimated polynomial channel matrix into a product of a paraunitary polynomial matrix and an upper triangular polynomial matrix with minimum phase filters on its main diagonal, where the polynomial pre-filter matrix is obtained by calculating the paraconjugate of the paraunitary polynomial matrix. The received data signal is demodulated (212) where the received data signal is multiplied with the calculated polynomial pre-filter matrix.

摘要： A receiver, in particular a VAMOS receiver, is provided. The receiver is adapted to split the complex-valued baseband signal into its real and imaginary parts. The two branch system thus created is modeled as a real-valued Multiple Input Multiple Output, MIMO, system. The receiver is further adapted to use correlations of the noise, both in time and between branches of a channel to suppress the noise for multi-users in the same channel. In accordance with one embodiment the receiver is adapted to take into account the known symmetries present in a symbol constellation when more than one user exists in the same channel. This is for example the case in adaptive symbol constellation such as an adaptive alpha - QPSK constellation. Using the receiver in accordance with the above can provide the same performance as a joint detection receiver in the presence of Gaussian white noise, while giving better interference suppression than either SAIC or joint detection in the presence of GMSK modulated interference.
摘要翻译：提供接收机，特别是VAMOS接收机。接收机适于将复值基带信号分解成其实部和虚部。由此创建的两个分支系统被建模为实数多输入多输出MIMO系统。接收机还适于在时间上和频道的分支之间使用噪声的相关性，以抑制同一信道中多用户的噪声。根据一个实施例，当多个用户存在于同一信道中时，接收机适于考虑存在于符号星座中的已知对称性。这是例如自适应符号星座的情况，例如自适应α-QPSK星座。在存在高斯白噪声的情况下，使用接收机可以提供与联合检测接收机相同的性能，同时在存在GMSK调制干扰的同时给出比SAIC或联合检测更好的干扰抑制。
