Provided are an apparatus and method for a hybrid multiple access wireless communication system. The apparatus comprises: a parameter acquisition unit configured to acquire a relevant parameter of a hybrid multiple access wireless communication system; and a sub-carrier allocation unit configured to use the relevant parameter to allocate sub-carriers to each user equipment with the purpose of optimizing overall communication quality of the hybrid multiple access wireless communication system.

Apparatus and method for hybrid multiple access wireless communication system

Provided are an apparatus and method for a sending end and a receiving end of a wireless communication system, and a soft information estimator. The apparatus for the sending end of the wireless communication system comprises: an interleave division multiple access unit configured to perform interleave processing on information to be sent; and a filter bank multi-carrier unit configured to use a specific sub-carrier chosen in advance to transmit the interleaved information in a parallel manner.

Apparatus and method for receiving and sending ends of wireless communication system, and soft information estimator

Provided is a wireless communication apparatus for a non-orthogonal multiple access communication system. The apparatus comprises: a power adjustment unit which is used, for at least some of user equipment included in the communication system, dynamically adjusting the sending power of each of the at least some of the user equipment for each sub-carrier according to channel state information about the communication system, in order that the at least some of the user equipment perform uplink data transmission on corresponding sub-carriers with the adjusted sending power. According to the disclosed apparatus, method and system, at least one of the following technical benefits could be obtained: increasing the channel capacity of the communication system; reducing the bit error rate during the communication; and reducing the interference between corresponding user equipment in the communication system.

Wireless communication apparatus and method, base station, user equipment and communication system

The present disclosure provides a signal processing system and method for a non-orthogonal multiple access communication system, a base station and a user equipment. The signal processing system is configured to perform interleaving processing on information to be transmitted subjected to modulation processing. The signal processing system can obtain at least one of the following beneficial effects: capable of saving length of an interleaver; and capable of obtaining more diversity gain.
