Abstract
A method includes, in a receiver, computing soft decoding metrics for decoding a received signal. The soft decoding metrics are stored in compressed form in a memory buffer. The soft decoding metrics in the compressed form are retrieved from the memory buffer, the retrieved soft decoding metrics are decompressed, and the received signal is decoded using the decompressed soft decoding metrics.
Claims21
A method, comprising:
- in a receiver, computing soft decoding metrics for decoding a received signal;
- storing the soft decoding metrics in a compressed form in a memory buffer;
- and
- retrieving the soft decoding metrics in the compressed form from the memory buffer, decompressing the retrieved soft decoding metrics and decoding the received signal using the decompressed soft decoding metrics.
1 more element
A telecommunication apparatus, comprising:
- a memory, which is configured to hold a memory buffer for storing soft decoding metrics;
- and
- processing circuitry, which is configured to compute the soft decoding metrics for decoding a received signal, to store the soft decoding metrics in a compressed form in the memory buffer, to retrieve the soft decoding metrics in the compressed form from the memory buffer, to decompress the retrieved soft decoding metrics and to decode the received signal using the decompressed soft decoding metrics.
A method, comprising:
- in a receiver, computing soft decoding metrics, wherein each soft decoding metric belongs to one of multiple decoding processes of a received signal;
- in a memory buffer, allocating a common region and multiple process-specific regions corresponding respectively to the decoding processes;
- dividing each soft decoding metric into a most-significant portion and a least-significant portion, storing the most-significant portion in the process-specific region corresponding to a decoding process to which the soft metric belongs, and storing the least-significant portion in the common region;
- and
- decoding the received signal using at least the most significant portions of the soft decoding metrics stored in the memory buffer.
