摘要: Certain aspects of the present disclosure provide an apparatus and techniques for efficiently processing uplink communications. A telecommunications receiver processor architecture is provided that may be utilized with a LTE eNodeB base station wherein the data path throughput is optimally matched for a Physical Uplink Shared Channel (PUSCH) receiver. According to certain aspects, the receiver may be configured to perform operations on OFDMs symbols in an interleaved order. Additionally, the receiver may instantiate multiple IDFT engines to process multiple OFDM symbols in parallel.

摘要: A method for optimizing a multiple input multiple output (MIMO) receiver for multiple antenna configurations is disclosed. A noise covariance is determined based on a noise estimate of a wireless signal. A Cholesky decomposition matrix is determined based on the noise covariance. A whitening matrix is determined based on the Cholesky decomposition matrix. The wireless signal is whitened using the whitening matrix.

摘要: Certain aspects of the present disclosure relate to a method and apparatus for processing wireless communications. According to certain aspects, a linked list of chunks of memory used to store logarithmic likelihood ratio (LLR) values for a transport block is generated. Each chunk holds LLR values for a code block of the transport block. The linked list is then provided to a hardware circuit for traversal. According to certain aspects, the hardware circuit may be an application specific integrated circuit (ASIC) processor or field programmable gate array (FPGA) configured to traverse the linked list of chunks of memory used to store LLR values.
