WebCDMA Architecture – Cell Breathing CDMA is a noise-generated technology. As such the system must monitor its noise floor or ambient noise. To much noise will cause interference leading to degraded service or dropped calls. CDMA systems are equipment with a protocol that allows the system to adjust in these situations. WebEncoding Example Figure 7.3 illustrates this CDMA spread spectrum. In the example, we encode two separate user bit streams: user 0 transmits the logical bitstream u 0 = [0, 1], which is physically represented by u 0 = [+1,-1]. Each bit is encoded (“spread”) by Walsh code 0: W 0 = [+1, +1, +1, +1], thus giving the represented symbol stream for user 0. …
