Burst-Mode Discrete Multi-Tone for Networks
First Claim
1. A method implemented by a first network element (NE), comprising:
- receiving, by a receiver of the first NE, a burst from a second NE, wherein the burst comprises at least one training symbol (TS);
storing, by a memory of the first NE, a channel response for a link between the first NE and the second NE, wherein the first NE is communicatively coupled to the second NE, wherein the channel response is based on a current channel response estimated using at least one TS in the burst and a previously stored channel response, and wherein the previously stored channel response is based on a plurality of bursts previously received from the second NE; and
compensating, by a processor coupled to the receiver and the memory of the first NE, modulated symbols in the burst using the channel response.

Abstract
A method implemented by a first network element (NE) comprises receiving, by a receiver of the first NE, a burst from a second NE, wherein the burst comprises at least one training symbol (TS), storing, by a memory of the first NE, a channel response for a link between the first NE and the second NE, wherein the first NE is communicatively coupled to the second NE, wherein the channel response is based on a current channel response estimated using at least one TS in the burst and a previously stored channel response, and wherein the previously stored channel response is based on a plurality of bursts previously received from the second NE, and compensating, by a processor coupled to the receiver and the memory of the first NE, modulated symbols in the burst using the channel response.

8. An optical line terminal (OLT), comprising:
-
a receiver configured to receive a burst from an optical network unit (ONU), wherein the burst comprises at least one training symbol (TS); a memory configured to store a channel response for a link between the OLT and the ONU, wherein the channel response is based on a current channel response estimated using the at least one TS in the burst and a previously stored channel response, and wherein the previously stored channel response is determined using a plurality of bursts previously received from the ONU; and a processor coupled to the memory and the receiver and configured to compensate modulated symbols in the burst using the channel response. - View Dependent Claims (9, 10, 11, 12, 13)

14. An optical line terminal (OLT), comprising:
-
a receiver configured to receive a burst from an optical network unit (ONU), wherein the burst comprises at least one training symbol (TS); a processor coupled to the receiver configured to; obtain the at least one TS from the burst; and generate a current channel response for the burst transmitted by a link between the OLT and the ONU; and a memory coupled to the processor and configured to store a channel response for the link between the OLT and the ONU, wherein the channel response is based on the current channel response and a stored channel response, and wherein the stored channel response is based on a plurality of bursts previously received from the ONU. - View Dependent Claims (15, 16, 17, 18, 19, 20)
