The received signal for the space-time block can be written as

5.52

where denotes the noise matrix during the period of a concerned space-time block.

Suppose that the channel matrix and noise satisfy Assumption 5.3. From Assumption 5.3 we have

5.53

5.54

5.55

Based on equations (5.51)–(5.55), we have

5.56

5.57

5.58

Substituting equations (5.56)–(5.58) into (5.50), we can obtain the likelihood function of for a given as follows:

5.59

Notice that for any two compatible matrices and , we have the following identity
