Description
y(i)=U(i)x、i=1,…,M
に従ってベクトルxに直交行列のそれぞれの1つを適用することによって、ベクトルxのM個の記述y(i)を生成する。
U=[u(0),u(1),…,u(N−1)]
によって与えることができ、ここで、u(i)、i=0,…,N−1は、その成分が乱数である長さNのベクトルv(i)、i=0,1…のシーケンスに直交化プロセスを適用することによって生成される直交ベクトルの集合である。
y(i)=U(i)x、i=1,…,M
U=[u(0),u(1),…,u(N−1)]
SL={p| ‖ε(i,p)‖>2δになるインデックスiを有する少なくともk+1個のメッセージがある}
を定義する。すると、集合SLおよびScは、共通部分を有しない、すなわち、SL∩Sc=ψである。大きいエラーを有するすべてのメッセージは、SL内にそのインデックスを有しなければならない、すなわち、‖e(i)‖>4δである場合には、i∈SLである。また、SLに含まれないインデックスを有するすべてのメッセージは、エラーを有しないか、小さいエラーを有するかのいずれかである。というのは、
