摘要： The present invention relates to a wireless communication system for downlink transmitting, through a plurality of orthogonal carriers and according to a non-orthogonal multiple access transmission scheme in a multiple-input single-output configuration, a plurality of messages towards, respectively, a plurality of users. At the transmitter side, a power allocation strategy subjected to a total power budget constraint and a linear filter computation based on the channel state information are jointly designed to meet a prescribed fairness constraint. The computed linear filter is adapted to balance interference caused to each user by the users being served at identical resources and is then used through an intra-carrier lattice-based non-linear precoding to mitigate the interference and also through a linear precoding to output a signal to be transmitted on the respective carrier towards each user. At the receiver side, the plurality of messages is finally recovered thanks to a simple single-user decoder.

摘要： The present invention relates to a wireless communication system for downlink transmitting, through a plurality of orthogonal carriers and according to a non-orthogonal multiple access transmission scheme in a single-input single-output configuration, a plurality of messages towards, respectively, a plurality of users. At the transmitter side, a power allocation strategy subjected to a total power budget constraint is implemented to meet a prescribed fairness constraint. The interference caused to each other by the users served at identical resources is efficiently mitigated through an intra-carrier lattice-based non-linear precoding process operating sequentially and taking account of the power allocation strategy, the users' ordering and the channel state information of each channel linking the respective carrier to each user. At the receiver side, the plurality of messages is respectively recovered by each user thanks to a respective simple single-user decoder, which decodes only its intended signal without requiring any successive interference cancellation procedure.

摘要： The present invention relates to a multi-antenna receiver (400B) within an uplink MIMO communication system (400), which comprises at least one RRU (400B-RRU) and at least one BBU (400B-BBU) communicating between themselves through a fronthaul (FH) link. The proposed multi-antenna receiver (400B) allows to significantly decrease the fronthaul (FH) throughput requirements, while guaranteeing a low EVM between the time‐domain signals transmitted from the users (400A) towards the RRU (400B‐RRU) and the signals reconstructed and recovered at the BBU (400B-BBU). The RRU (400B-RRU), which is provided with frequency processing functionalities, processes the obtained frequency‐domain signals in a space of dimensionality N by projecting them into a signal space of lower dimensionality (N') and compressing them in the obtained projected signal subspace. At the BBU (400B-BBU), the frequency‐domain signals are decompressed and reconstructed on the projected signal subspace, before recovering the transmitted time‐domain signals.

摘要： The present invention relates to reception of radio frequency (RF) signals from one or more user communication devices at N RF signal receiving devices, wherein N is a positive integer, and to processing of the received RF signals by the one or more RF signal receiving devices. A RF signal receiving device decompresses compressed output signals received from one or more RF signal receiving devices of the N RF signal receiving devices and generates a compressed output signal by executing a signal compression with regard to the decompressed signals and with regard to a RF signal received by the RF signal receiving device. Additionally, the present invention is directed to a further processing of output signals of a RF signal receiving device of the N RF signal receiving devices at a signal processing device.
