Abstract (in Japanese) (See Japanese page) 
(in English) For an accurate BER analysis over spatially correlated MIMO channels, this report derives average BER bounds by using two-dimensional (2D) pairwise error probability (PEP), and evaluates their accuracy. A union bound for average BER over the spatially correlated MIMO channels has already been obtained. However, the union bound is not tight at low average $E_b/N_0$ because the decision error probability of transmitted signal sequence is approximated as codeword one-dimensional (1D) PEP. Union bounds for average BER using codeword 2D-PEP or symbol 2D-PEP are more accurate than the one using 1D-PEP. The codeword 2D-PEP can be applied to all space-time codes for MIMO. On the other hand, the application of the 2D-PEP is limited to the orthogonal code such as OSTBC because it requires the MIMO channel to be decomposed into orthogonal channels by a space-time code and so on. We theoretically derive the above three average BER bounds, clarifies their relation, and evaluates their accuracy by computer simulations.
