Methods and systems for improved channel estimation in multi-carrier systems

A wireless receiver device, comprising:

• means for loading a first method of deriving a channel estimate, the first method using a method of channel estimation advantageous in reception situations having high Doppler spreads;
• means for loading a second method of deriving a channel estimate, the second method using a method of channel estimation advantageous in reception situations having low Doppler spreads;
• means for selecting one of the first method and the second method of deriving a channel estimate based on channel characteristics;
• and
• means for using the selected method to derive the channel estimation.
