摘要： By exploiting the multi -block structure of the used slot format having a training sequence in the time domain and at least one pre-coded user data block to sequentially reconstruct the slot, using in the first step known symbols and using detected symbols in each subsequent step and improved receiver can be provided. This can result in less ISl/lBI and therefore increased performance. A training sequence known at the receiver is used for channel estimation. The channel estimation is used to reconstruct the value of the received block containing the training sequence. The reconstructed block is subtracted from the received block and an overlapping and add algorithm is applied to the substracted result and the previous block. Finally, the method is recursively applied for the preceedings blocks.

摘要： In a radio system node, such as a Base Transceiver Station (BTS), a compensation unit is provided to convert information about downlink signal strength in a measurement report received from a mobile station when the signal to the mobile station is transmitted using several co-channel signals transmitted simultaneously in the same time slot and at the same frequency.

摘要： A receiver is provided that is configured to estimate the symbol constellation of a signal modulated using a quaternary symbol constellation where data is transmitted to two mobile stations multiplexed on a shared channel comprising two branches, where the branches correspond to the real and imaginary parts of one complex-valued baseband signal. The receiver is configured to demodulate the modulated signal using the training sequences from both sub-channels.
摘要翻译：提供了一种接收机，其被配置为估计使用四进制符号星座调制的信号的符号星座图，其中数据被发送到在包括两个分支的共享信道上复用的两个移动台，其中分支对应于一个的实部和虚部复值基带信号。接收机被配置为使用来自两个子信道的训练序列来解调调制信号。
