The Next Codeword Pointer (NCP) is a portion of the downstream OFDM channel which is dedicated to carry information about the mapping of FEC codewords to subcarriers within a symbol.
OFDM PLC errors on MB8600. on Firmware 8600-19.3.15. Is anyone else seeing no errors on the event log, no uncorrectable errors occuring on anything but Channel 33 OFDM PLC where they are at roughly 400,000,000 in less than 48 hours. Wondering if it's an issue with the firmware but can't find a reliable reference.

Consider an OFDM system with total passband B = 5 MHz with N = 512 sub-carriers. The channel has a maximum delay spread of Td = 4 ps. Answer the following questions. (15 Marks) (a) What is the symbol time of a corresponding single-carrier system? (2 Marks) (b) What is the sample time of the OFDM system and the raw symbol time without the cyclic ...

Question: Suppose that Nc=1024 subcarriers are used in an OFDM system with bandwidth of 1MHz over a fading channel with delay spread of 4μs. 1) What is the maximum achievable diversity order? 2) How to achieve the maximum diversity order? 3) How many independent symbols can be transmitted simultaneously at most each with full diversity gain? State your reason.
