They are +more or less ordered according to their benefit, but that is subjective +to some degree. + +Unless written, no activity has been started on the topics. + + +TII implementation incorrect +---------------------------- +The current TII implementation is wrong. There are two TII variants: +one according to spec, and the one that was implemented in early modulators +that ended up being used a lot even if not compatible with the spec. + +ODR-DabMod should support both ideally. + + +EDI input +--------- +Add support for EDI input, so that more multiplexers can be interfaced +to the modulator. Relevant spec: ETSI TS 102 693 + +It would be beneficial to write and EDI decoding library that can be re-used in +ODR-DabMux to add EDI input there too for encoders. + +Initial work started in http://git.mpb.li/git/odr-edilib/ + + +Review CicEq +------------ +The CIC Equaliser was used for the USRP1 to compensate for spectrum flatness. +It is not documented, and its effect poorly explained. Review if still needed, +and document appropriately. + + +Add metadata to flowgraph +------------------------- +The flowgraph does not support metadata. This is why the timestamp has this +kludge with the delay queue, so that the timestamps are delayed properly +depending on what is included in the flowgraph. + +Without metadata inside the flowgraph, it is more difficult to pipeline the DSP +processing to make use of many-core systems, because the timestamp cannot be +carried alongside the data it corresponds to. |
