Abstract
A transmitter apparatus in a wireless communication system that includes a processor. In one embodiment, the processor is configured to receive at least one modulated data message and spread the at least one modulated data message into a transmission signal using a low density signature matrix. The low density signature matrix is a cycle-free signature matrix. A receiver apparatus is configured to receive the transmission signal and detect within the received transmission signal at least one modulated data message. The processor is configured to detect the at least one modulated data message in one iteration using the cycle-free signature matrix.
Claims15
A transmitter apparatus for a wireless communication system, the transmitter apparatus comprising a processor configured to:
- receive at least one modulated data message;
- and
- spread the at least one modulated data message into a transmission signal using a low density signature matrix, wherein the low density signature matrix is a cycle-free signature matrix.
A receiver apparatus for a wireless communication system, the receiver apparatus including a processor configured to:
- receive a transmission signal;
- and
- detect within the received transmission signal at least one modulated data message, the processor being configured to detect the at least one modulated data message in one iteration using a cycle-free signature matrix.
A radio access network comprising a transmitter apparatus for a wireless communication system, the transmitter apparatus comprising:
- a processor configured to:
- receive at least one modulated data message;
- and
- spread the at least one modulated data message into a transmission signal using a low density signature matrix, wherein the low density signature matrix is a cycle-free signature matrix;
- a receiver apparatus including a processor configured to:
- receive a transmission signal;
- and
- detect within the received transmission signal the at least one modulated data message, the processor being configured to detect the at least one modulated data message in one iteration using a cycle-free signature matrix.
A method for non-orthogonal transmission in a wireless communication system, the method comprising:
- selecting at least one data message for transmission;
- encoding and modulating the at least one data message;
- interleaving the encoded and modulated at least one data message;
- and
- spreading the encoded, modulated, and interleaved at least one data message into a transmission signal using a cycle-free signature matrix.
A method for non-orthogonal reception in a wireless communication system, the method comprising:
- receiving a signal;
- and
- detecting, in one iteration using a cycle-free signature matrix, at least one modulated data message in the received signal.
