| Abstract: |
| According to the character of GSM signal, the signal processing algori
thm of locating MS(Mobile Station) based on TDOA(Time Difference of Arrival) is
proposed. Then the method of determining arrivin
g-time of MS and the precise estimation technology of time-delay are discussed o
n t
he basis of equalization demodulation, and the solution of localization equation
is described. Finally,the signal processing algorithm is evaluated and the resu
lts show the feasibility of the algorithm. |
