<p>A maximum likelihood estimation method for a MIMO system includes the steps of: estimating each received signal, and generating J maximum likelihood estimated values, wherein J is 1= J =S, S is the number of the received signals under all possible situations; generating the sequence of all possible received signals based on the J maximum likelihood estimated values of each received signal; calculating the Euclidian Distance corresponding to each possible received signal sequence, and finding out the minimum Euclidian distance; outputting the received signal sequence corresponding to the minimum Euclidian distance. A maximum likelihood estimation apparatus and receiver for a MIMO system are also provided. By applying this method, the apparatus and the MIMO system, the search space of the received signal sequence is furthest reduced and the calculating quantity is observably reduced, and the applicability is furthest enhanced, the signal detecting capability of the maximum estimation method of this invention approximates to the optimal one.</p> |
