To stitch the common information at different blocks of URA, a modified tree decoder is proposed to take the IM constraint into account. At the receiver, the covariance-based maximum likelihood detection (CB-MLD) is employed to recover the active compressed sensing (CS) code words of URA and information of SRA jointly. IM-aided SRA allocates multiple pilot sequences to each user and activates only one pilot sequence whose index carries the data information. Practically, IM-aided URA partitions channel blocks of one transmission frame into multiple groups and then employs the IM principle to activate only part of the channel blocks in each group. In this scheme, common information is transmitted by index modulation (IM)–aided unsourced random access (URA), while user-specific information is by IM-aided sourced random access (SRA). In this study, a mixed massive random access scheme is considered where part of users transmit both common information and user-specific information, while others transmit only common information.

I hope! Old dog or not, Massive still has lot of bite and I love its tricks, not to mention the investments made in feeding the beast with expansions. I heard a lot of hard drive activity so I just left each version open for a while thinking that there might be a bunch of first-start operations being taken care of and, my imagination or not, everything seems to be running normally on subsequent starts. Things were sluggish and unstable the first time I opened each version (although the Browser Tab seems to work faster/better-even though the somewhat irritating propensity to have the view of every NI Expansion expanded to its folders).

When I opened the stand-alone, It started with a different preset-just the first one in the dropdown list. When I started my DAW (Reaper6), it scanned Massive.dll and loaded my templates with Massive with the presets I had set. I selected 'Install' instead of 'Repair' and it seemed to complete the update (at least in Native Access).

I got the green 'Installed' checkmark in the updates window of Native Access but I got an orange error message in the 'Installed' window, something about missing the 32-bit Massive plugin.
