Application of the PR principle to combat intercellular interference in cellular CTDMA

Code time division multiple access (CTDMA) was shown earlier to be a CDMA type air interface suitable for future personal communication systems (PCS). It outperforms other proposals due to its low-complexity receiver implementation that avoids intracell interuser interference. This paper investigates the performance of an enhanced medium complexity receiver structure based on the projection receiver (PR) principle in order to reduce the intercell interference
