A retention assembly for securing a optical disc drive (ODD) to a main frame of an electronic device includes a bracket and a connector. The bracket is fixed to the ODD. One of the main frame and the bracket defines a guide groove, and the other includes a slide rail movably received in the guide groove. The connector is fixed to the main frame and adjacent to the guide groove or the slide rail. The ODD is aligned to electrically connect to the connector by the at least one guide groove or the at least one slide rail.

A method and apparatus for a receiver comprises: a plurality of paths with each path associated with an independent antenna. Each path comprises: a channel estimation device associated with a particular channel; and a set of parameters denoting channel characteristic associated with each path. The receiver further comprises a time de-interleaver or FEC decoder shared by the plurality of paths. Whereby at least one device that use significant amount of memory is shared by the plurality of paths.

In a decoder having an improved LLR (log-likelihood-ratio) update method is provided. The method comprising the steps of: providing a parity check matrix; and using merely a set of parameters on a row of the parity check matrix instead of data of the whole non-zero elements of the parity check matrix free from at least one shifting action after each row updating; thereby saving memory space and process time.
