摘要： A communication method for use in a first cellular communications system is proposed for minimizing the interference caused by strong interfering pulses in the same frequency band as the system or an adjacent frequency band. The method comprises the steps of receiving an incoming signal bandpass filtering the incoming signal to filter out a first frequency band (B1) used by the communications system and forwarding the bandpass filtered signal to a receiver unit (35) for processing and forwarding the processed signal to a signal detector (37) arranged to detect the wanted signal. Redirecting a fraction of the received signal and detecting the power of the redirected fraction. Using the detected power to modify the function of the signal detector (37).

摘要： Signal properties of a signal section (106) comprising a training sequence are compared with corresponding signal properties of other signal sections (108, 110). At a too large discrepancy, co-sequence interference is concluded to be present. The used signal property can preferably be a signal-to-noise ratio measure or a signal statistics measure. If the existence of co-sequence interference (102) is concluded, measures can be taken to avoid such interference and to mitigate the effects of the interference. A method for mitigating effects of co-sequence interference in channel estimation comprises a joint detection and estimation procedure performed under constrictions assuming presence of co-sequence interference.

摘要： The invention provides a scheduling of data blocks on multiple data carriers and a selection of data carrier to listen to. A transmitting unit simultaneously transmits, during a communication session with at least one participating receiving unit, at least a first data block on a first data carrier and a second data block on a second data carrier. The receiving unit selects which of these data carriers to listen to, i.e. whether to receive the first or second data block, based on a reception quality of a previously received data block. Furthermore, at least one of the first and second data block is based on information common to the data block and the previous data block, e.g. the first or second data block could be re-transmitted version of the previous block.

摘要： When transmitting data from a transmission unit to a reception unit over a channel in a wireless communication system, it has been observed that there are inherent losses in throughput, especially for a channel experiencing high channel quality variations over its frequency range. To improve the throughput over such a channel, it is proposed to: estimate the quality of each subchannel of a channel, classify the subchannels into a number of quality groups based on the estimated quality, and select a code rate per quality group. This selected code rate per quality group is then used when a data word to be transmitted is coded. Simulations have shown that by grouping the subchannels into a limited number of groups, for example one to four groups depending on the channel quality variation, a high throughput could be achieved with a minimum of signaling cost in the form of extra overhead.
摘要翻译：当通过无线通信系统中的信道将数据从传输单元发送到接收单元时，已经观察到吞吐量存在固有损失，特别是对于在其频率范围内经历高信道质量变化的信道。为了提高这种信道的吞吐量，建议：估计信道的每个子信道的质量，并根据估计的质量将子信道分类成多个质量组，并且选择每个质量组的码率。然后，当要发送的数据字被编码时，每个质量组的该选择的码率被使用。模拟已经表明，通过将子信道分组为有限数量的组，例如根据信道质量变化的一到四组，可以以额外开销的形式以最小的信令成本来实现高吞吐量。
