An reception device includes: a fast-fourier-transform (FFT) circuit to FFT a first Orthogonal Frequency Division Multiplexing (OFDM) signal including a plurality of first symbols with a guard interval and a valid symbol using a plurality of FFT windows that includes different timings within a symbol length period; a propagation channel...
FreshPatents.com Interpolated channel estimation for mobile ofdm systems
In an OFDM system using pilot cells for channel estimation, time interpolation among pilot cells of different OFDM symbols is commonly used to improve the estimate. The estimated channel impulse response is also windowed to further reduce noise and disturbances. However, for a transmission over a time-varying channel, suboptimal time...
