Tie a wee bit of something, even a strip off a plastic bag, round the bottom of the fruiting canes, now. Those are your Autumn ones.
Then take each cane one at a time and if it's totally brown and hard and brittle, cut it right out from the base. Those are dead and won't come again.
Now look at the unmarked canes that are left. Those are most likely your Summer ones, and they need pruned differently to the Autumn ones. The Autumn ones can be cut right down and will fruit on canes that grow next year. The Summer ones fruit on the new canes that grew this year and this year's old fruited canes need cut out, they won't fruit again. I cut my Autumn ones back when they've lost all leaves and gone brown. I know it's a bit early, but mine aren't trained onto wires, and it's easier this way.
The RHS says,
"Pruning
Regular annual pruning will result in healthier plants, and better quality crops.
Summer-fruiting raspberries
Cut back fruited canes to ground level after harvesting; do not leave old stubs
Select the strongest young canes, around six to eight per plant, and tie them in 8-10cm (3-4in) apart along the wire supports
Remove the remaining young stems to ground level
Autumn-fruiting raspberries
Cut back all the canes to ground level in February. Reduce the number of canes slightly in summer if they are very overcrowded."
