Aspects of a method and system for efficient full resolution correlation may include correlating a first signal with a second signal at a rate corresponding to a first discrete signal, wherein each sample of the first signal may be generated by summing a plurality of consecutive samples from the first discrete signal, and the second signal may be generated by summing the plurality of consecutive samples from a second discrete signal. The correlating may be performed by a matched filter and/or a correlator. The first signal comprising N samples may be generated by summing L consecutive samples for each of the N samples from the first discrete signal comprising N*L samples. The second signal comprising N samples may be generated by summing L consecutive samples for each of the N samples from the second discrete signal comprising N*L samples. The first signal and the second signal may be correlated by multiplying the N samples of the first signal with the N samples of the second signal in N multipliers and summing a plurality of outputs of the multipliers. A maximum of the correlating may be determined to achieve synchronization between the first discrete signal and the second discrete signal.

Method and system for efficient full resolution correlation

A mobile device receives a signal, from a base station, comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device utilizes two different sampling rates to perform the PSS synchronization and the SSS detection individually. For example, the mobile device synchronizes to the received PSS at a first sampling rate such as 0.96 MHz, which is determined based on the PSS transmission rate and/or the length of the received PSS. The mobile device detects the received SSS at a second sampling rate such as 1.92 MHz, which equals to the sampling rate for an analog-to-digital conversion at the mobile device. The received PSS and associated symbol timing are detected through the PSS synchronization to support the SSS detection. The detected SSS is used to acquire cell-specific parameters such as cell ID. The acquired cell-specific parameters ensure proper communications between the mobile device and the base station.

A mobile device estimates channel state information (CSI) comprising, for example, CQI and/or SNR, for a downlink channel. The estimated CSI is non-uniformly quantized and transmitted to the base station over a finite-rate feedback channel. Different portions of the estimated CSI are quantized using different quantization step sizes, which are determined according to a performance metric function such as a channel capacity function of the estimated CSI. A quantization step size for a portion of the estimated CSI is increased if a low distribution probability is indicated by the portion of the estimated CSI. A quantization step size for a portion of the estimated CSI is decreased if a high distribution probability is indicated. The mobile device quantizes the estimated CSI using the determined quantization step sizes to transmit to the base station over the finite-rate feedback channel. Downlink data transmission is received according to the transmitted CSI.

A mobile device receives a radio frequency (RF) signal comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device performs multiple frequency hypothesis (MFH) testing via multiple MFH branches. A SSS decoding and a PSS correlation process are performed, respectively, per MFH branch.
