Mark Hughes' men are yet to taste victory this season, and suffered their fourth defeat of the season on Monday night when they were beaten 2-1 by newly-promoted West Ham.
The result left the Rs rooted to the foot of the Premier League table, however Ferdinand believes that they have the quality to end their winless run and move away from the bottom three.
He told QPR's official website: "We have got an impressive squad and I’m sure if we keep playing as we have been in recent weeks, we will turn things around.
"It has to turn at some point and let’s hope it’s sooner rather than later."
The 27-year-old also paid tribute to the QPR fans for the backing he received during their recent clash with Chelsea, the first time that the two teams had met since Blues' captain John Terry was cleared by a court of racially abusing Ferdinand in a clash between the sides last season.
He added: "The fans were great and I want to thank them from the bottom of my heart. They gave me fantastic support and I couldn’t have got through the day without them. They kept me going for the full 90 minutes.
"It has been a difficult period for me but the fans have been special, they have been very good to me. I just want to concentrate on football now and look forward to climbing up that table."
