    Abstract: Aspects of a method and system for preserving content timing across femtocell interfaces via timestamp insertion are provided. In this regard, a femtocell may receive a first time-stamped packet via a first interface and transcode the time-stamped packet. The femtocell may buffer the transcoded packet based on a time-stamp recovered from the packet and may transmit the buffered transcoded packet via a second interface. One of the first interface and the second interface may utilize the Internet Protocol. One of the first interface and the second interface may be a non-cellular interface and the other interface may be a cellular interface. The femtocell may be operable to generate a timestamp corresponding to a time instant at which a time-stamped packet arrived via the first interface or the second interface. The timestamp may be referenced to a clock within a cellular enabled communication devices communicatively coupled to the femtocell.

    Abstract: A mobile device accumulates energy associated with each of successive PSS transmissions received from a base station. Accumulated energy values may be rescaled by a same number of bits whenever a buffer overflow condition occurs within the accumulation buffer. The mobile device may detect a correct PSS timing hypothesis utilizing the rescaled accumulated energy values within the accumulation buffer. A significant bit such as, for example, the most significant bit (MSB) or one of lesser significant bits, of each of the accumulated energy values may be monitored during the energy accumulation process to detect a buffer overflow condition. The mobile device may determine number of bits for rescaling or right shift each of the accumulated energy values in response to the detected buffer overflow condition. The resulting shifted accumulated energy values may be utilized for PSS detection. Either an integrating or filtering method is utilized during the energy accumulation process.

    Abstract: Aspects of a method and system for a delta quantizer for rate reduction pre-coding matrices may include quantizing a change in channel state information in a MIMO pre-coding system onto a codebook and generating a pre-coding matrix based on at least the channel state information. The channel state information may be a matrix V and one or more associated singular values. The matrix V may be generated using Singular Value Decomposition (SVD) or Geometric Mean Decomposition (GMD). One or more columns of the matrix V may be selected based on the one or more associated singular values and may be combined to enable the generation of the pre-coding matrix. The codebook may comprise one or more unitary matrices. An index of an element of the codebook, onto which the change in channel state information is quantized, may be transmitted from a receiver to a transmitter.

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.
