HELLO EVERYBODY! I'M TRYING TO COMPARE MC-CDMA AND MC-DS-CDMA USING SINGLE USER AND MULTI-USER DETECTION TECHNIQUES IN TERMS OF BIT ERROR RATE AND SPECTRAL EFFICIENCY IN A MOBILE COMMUNICATION USING MATLAB.THAT IS USING DIRECT SEQUENCE SPREAD SPECTRUM(TRANSMITTING THE CHIPS OVER SEVERAL SUB-CARRIERS),PERFORMING THE MULTI-CARRIER MODULATION AND DEMODULATION USING IFFT AND FFT OPERATIONS, SEPARATE THE USERS' SIGNALS IN THE CODE DOMAIN. BY THE WAY, I HAVE NO PROBLEM WITH THE THEORETICAL PARTS,CAN ANYONE HELP ME PLS? THANKS IN ADVANCE! BEST REGARDS!

My ASR-33 had an extra-high type cylinder and two extra selector bars that gave it lower case. They were never marketed, but prototypes had been made and I got a hold of a set of spare parts. The whole A/KSR-33 project was kept secret from management until there were working models, and even then they were kept off the market in order not to compete with the ASR-35. When TTY Corp finally did decide to market a KSR-33, having it do lower case was simply unacceptable.

I don't know what it was called, though. Steve

The original design before it was dumbed down. Jerry -- Engineering is the art of making what you want from things you can get. ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
