METHOD AND APPARATUS TO COMPUTE A NOISE POWER ESTIMATE IN A WCDMA NETWORK BASED ON DEDICATED PHYSICAL CONTROL CHANNEL (DPCCH) PROCESSING

摘要

A method to process DP bits within a WCDMA receiver where a noise estimation that may be implemented within hardware is provided for improved flexibility and performance. DPCH pilot symbols are received, quantized, channel compensated and combined. The computation of an SNR estimate based on the combined DPCH pilot symbols is provided. Noise estimation is used as part of the SNR estimation of the DP bits (used for downlink power control). This method does not rely on the assumption that the channel is constant over the DP field, while prior methods did.
