Symbol detection of massive MIMO systems with unknown symbol-dependent transmit-side impairments

A system for processing a perturbation quantity received in a wireless network, the perturbation quantity including a non-linear effect from at least one transmitted signal of the wireless network, wherein at least one Base Station (BS) includes at least one antenna configured for data transmission, such that the BS is configured for wireless communication with a User Equipment (UE) in the wireless network, and the BS is configured to establish a link between the BS and the UE, to provide a plurality of transmitted and uplink data streams, the system comprising:

• a processing circuit, configured to
• implement receiver-side decoders, wherein at least one receiver-side decoder of the receiver-side decoders is configurable to
• provide a remotely configurable recovery of unknown symbols perturbed by the perturbation quantity, wherein the recovery is at a receiver-side and the perturbation is at the transmitter-side, such that the receiver is either for an uplink transmission at the BS or for a downlink transmission at the UE;
• and
• provide receiver-side decoding for symbol detection of symbol-dependent transmit-side perturbations by imposing a hierarchical signal model on the transmitted symbol, and wherein the decoding that is provided by the receiver-side decoders is used to recover the unknown symbols perturbed by the perturbation quantity and to identify symbol dependent perturbations, to reduce an amount of decoding processing costs by either the UE or the BS;
• and
• a control element in communication with the processing circuit to implement an action, based on the recovery of the unknown symbols perturbed by the perturbation quantity.
