Spacetime block code (STBC)[14] 

Description

In a space-time block code, \(n\) spatially separated channels transmit symbols in \(T\) time slots. These symbols can be arranged in a \(T\times n\) matrix where the columns correspond to the channels, and the rows correspond to the time slots. The codewords \(\{X\}\) are \(T\times n\) matrices such that the codeword difference matrices have rank \(n\), and \(\min_{X\neq 0}\det(XX^*)\) is maximized.

Protection

Provides protection against errors due to thermal noise and destructive interference arising from traversing an environment with scattering, reflection, and/or refraction.

Realizations

High data-rate wireless communication, e.g., WiMAX (IEEE 802.16m) [57].

Parent

  • Spacetime code (STC) — Spacetime codes also use spatial and temporal diversity, but do not necessarily use blocks as codewords.
