Narrative:

I taxied to runway 31 and did my run-up checks, then held short of runway 31 on taxiway H, still listening to the ground frequency. My call sign was XXX and I heard 'xxy cleared for takeoff' on the ground frequency, which I thought was my call sign and I lined up on runway 31 and took off. Soon after takeoff, I saw a large aircraft departing runway 4. I then leveled off to avoid a collision with the aircraft. After I was clear of the aircraft, I continued outbound on runway heading. After 1 min, tower called me and requested that I call them when I land. After this, I continued on my heading for about 10 mi. At this point, I turned around and headed back to tyler airport, landed, and taxied back to parking and contacted the tower as requested. Contributing factors: 1) 2 aircraft with similar call signs (XXX and xxy). 2) tower was transmitting over the ground frequency. 3) it was not possible to see another aircraft line up on runway 4. Corrective actions: 1) saw the other aircraft on my left and then leveled off. 2) contacted tower and chief flying instructor when back on the ground. 3) having 2 hours training and a dual chkout with CFI.
