The MH-SSCD sequentially tests more than two hypotheses.
This is termed the “sequential multihypothesis test.” There
have been some recursive methods that obtain the optimal
stopping time and final decision for the sequential multihypothesis
test.However,these methods are impractical due to
their high complexity.In [13],a suboptimal method,called the
𝑀-ary sequential probability ratio test (MSPRT),is proposed.
The complexity of MSPRT is low,and its performance is
asymptotically optimal as the cost per observation (i.e.,𝑐)
approaches to zero.Thus,we utilize the MSPRT to find the
optimal stopping time and final decision of the MH-SSCD.
