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.
ECED 3511 Final Exam 2015 4 Problem 3: (OFDM) Consider an OFDM system with a 128 sub-carriers separated by 4.125 MHz. 1. Compute the following parameters What is the maximum possible symbol rate on each subcarrier? . If QPSK is used on each subcarrier what is the maximum possible bit-rate overall? What is the time length of one OFDM symbol? 2.
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.
As far as I know Cox only supports 1 downstream OFDM channel and 0 upstream OFDM channels at this time in all areas. 1 OFDM channel is more than enough to support fill gigabit speeds.
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 ...
