Abstract
In LTE system, blind detection of traditional antenna port number detection generated a lot of computational redundancy and delay. To solve this problem, an improved detection algorithm based on channel estimation and piecewise linear regression is proposed. This algorithm fits the phase information of channel state and determines the number of antenna ports. The problem of decision error caused by phase jump is solved by piecewise. The theoretical analysis and simulation results show that the proposed algorithm has the advantages of low complexity and delay.
