| titleOfInvention | Unitary precoding for Lattice Reduction Aided MIMO communication |
| abstract | In a Multiple In Multiple Out (MIMO) communications system, transmissions are precoded 300 using a unitary matrix <B>W</B> derived from channel information 310 fed back from the receiver 320, allowing Lattice Reduction (LR) aided detection/decoding at the receiver using less computational complexity. A received estimated channel matrix <B>H</B> is decomposed via Geometric Mean Decomposition (GMD) into a unitary matrix <B>Q</B>, an upper triangular or diagonal matrix <B>R</B> (<B>=HW</B>) and the Hermitian transpose of a second unitary matrix <B>W</B>, and the transmitted data x is then precoded by multiplying it by <B>W</B>. The method accommodates linear (eg. Zero Forcing ZF or Minimum Mean Square Estimation MMSE) or nonlinear (eg. Sphere or Lenstra Lenstra Lovasz LLL) decoding, and average power per antenna is also balanced. |
