Radio base station and radio mobile station |
摘要 |
The base station transmits a synchronization signal that contains a pattern of repeated SYNC's generated by dividing FFT size by N wherein the pattern of repeated SYNC's is inverted in polarity for each of the SYNC's according to a code outputted from a code generating circuit. CP length is M/N of FFT size, and the number of divisions (M+N) of a symbol of the synchronization signal is brought into agreement with the code length L of Barker code. The mobile station detects the synchronization signal by using a first matched filter that has as many taps as (FFT size/N) stages, and uses a pattern of SYNC's generated by dividing FFT size by N as a tap coefficient, and a second matched filter that has as many taps as (M+N) stages and uses Barker code as a tap coefficient. |
