Performance Analysis of Decorrelating Decision Feedback Detection for MIMO Systems in Rician Fading
نویسندگان
چکیده
The diversity gain of the joint error probability (JEP) of the decorrelating decision feedback detector (D-DFD) for multiple-input multiple-output (MIMO) systems in the presence of Rician fading is considered. Upper bounds on the JEP are derived for both M-ary Phase-Shift-Keying (PSK) and M-ary Quadrature Amplitude Modulation (QAM). It is shown that the diversity gain of the D-DFD receiver in both cases is equal to NR − NT + 1 where NR and NT are the number of transmit and receive antennas, respectively. As an aside, the Bartlett decomposition of a complex non-central Wishart matrix is also derived.
