Increased spectral efficiency and reduced synchronization delay with bundled transmissions

摘要

Techniques are provided for increasing spectral efficiency over data channels in a storage or communication system. In some embodiments, data may be encoded and transmitted over multiple channels. The transmitted data from the multiple channels may be considered together as a channel bundle, thereby increasing the edge transitions of the group of signals to improve clock recovery and reduce coding constraints. In some embodiments, the channel bit size is reduced to maximize data rates based on the reduced coding constraints. Furthermore, the channel bundle has only one channel with timing markers, so that a receiver may receive information from the channel bundle and recover clocking based on the timing markers in the one channel.

1. A method of communicating data, the method comprising:
encoding source data into encoded data; transmitting the encoded data over a channel bundle comprising multiple channels, wherein the multiple channels comprise only a single channel with a timing marker; receiving the encoded data from the multiple channels with a decoder, wherein the encoded data received by the decoder from the multiple channels transmitted over the channel bundle is decoded together jointly; and recovering clock information from the single channel of the channel bundle with the timing marker.
