ABSTRACT
Assume that the output of baseband filter is sampled at tomes the chip rate, the Cycle time of the chip is 31. The coefficient matrix of the Linear equations (7) is (9).
Basic idea of MUSIC algorithm: Discrete measurement data can be got by L values of ( )H f which is the frequency response under the same frequency interval sampling. Consider the impact of Gaussian white noise, frequency response of sampled discrete channel is :
∑ω α ω= + = +pi τ− + ∆ =
( ) ( ) ( ) ( )2 ( )
0x l H f l e ll k j f l f
(10)
It can be written as formula (11), which is a vector matrix
The MUSIC algorithm in here is broken down the matrix X in the formula (11).
