1. A method for receiving information over a power line, comprising:
- separating the data within a payload of an incoming frame into a plurality of blocks, the incoming frame including frame control symbols and data; and
processing both the frame control symbols and the data within the blocks by Frame Control Forward Error Correction (FEC) decoding logic, the processing of both the frame control symbols and data of the payload are conducted by de-interleaving and decoding operations.

Abstract
In one embodiment, a system and method for receiving information over a power line in accordance with the HomePlug specification is described. The receiver side of the method involves separation of the data within a payload of an incoming frame into a plurality of blocks. Thereafter, both frame control symbols and data within the blocks are processed by Frame Control Forward Error Correction (FEC) decoding logic.

11. A method comprising:
-
determining whether a HomePlug compliant station is operating in a low-rate automation control (LORA) mode;
encoding both control information and data within a Frame Control Forward Error Correction (FEC) encoding logic if the HomePlug compliant station is operating in the LORA mode; and
upon determining that the HomePlug compliant station is not operating in the LORA mode, producing frame control symbols for a frame by the Frame Control FEC encoding logic, and producing data corresponding to a payload of the frame by a Data FEC encoding logic. - View Dependent Claims (12, 13, 14, 15)

16. Software embodied in a machine-readable medium and executed by a processor, comprising:
-
a first software module to separate data within a payload of an incoming frame into a plurality of blocks, the incoming frame including frame control symbols and data; and
a second software module to process both the frame control symbols and the data within the blocks by conducting de-interleaving and decoding operations, the second software module operating as a Frame Control Forward Error Correction (FEC) decoding logic.

17. A HomePlug compliant station comprising:
-
a media access control (MAC) layer; and
a physical layer in communication with the MAC layer, the physical layer including a Frame Control Forward Error Correction (FEC) encoding logic to encode and interleave both data and control information associated with a frame during a first mode of operation and a data FEC encoding logic that, during a second mode of operation, encodes and interleaves the data while the Frame Control FEC encoding logic encodes and interleaves only the control information. - View Dependent Claims (18, 19, 20)

21. A HomePlug compliant station comprising:
-
a receiver to retrieve an incoming frame from a power line; and
a Frame Control Forward Error Correction (FEC) decoding logic, coupled to the receiver, to de-interleave and decode both data and control information associated with the incoming frame during a first mode of operation and to de-interleave and decode only the control information during a second mode of operation. - View Dependent Claims (22, 23, 24, 25)
