<p>Techniques are disclosed for channel estimation in rapidly changing environments. In one aspect, a difference estimate (630) is updated when a current received symbol comprises a difference between the primary and diversity channels (614), and a sum estimate (620) is updated when a current received symbol comprises a sum of the primary and diversity channels (612). The primary channel and the diversity channel are estimated from the sum estimate and the difference estimate (640). This has the benefit of incorporating the most recently received symbol, resulting in more accurate channel estimates and hence improved demodulation performance, increased system capacity, and lower required transmit power.</p> |
