- Date Issued
- In this thesis, a training sequence set for a multiple-input and multiple-output (MIMO)
system adopting a training-sequence scheme is proposed. The training sequence set is derived
using the least-square approximation (LSA) and named partial-period zero-correlation zone
(PZCZ) sequence set because of its correlation property. A PZCZ sequence set achieves
minimum mean-square error (MMSE) in a frame structure in which training sequences are
placed ahead of information.
The properties of PZCZ sequence sets and the methods of designing and extending the
sequence set are also given.
Index Terms ？ Autocorrelation function, cross-correlation function, least-square
