Adaptive MLSE receiver for dual-band IS-136 TDMA
Angel Lozano, G.M. Peponides · 2002
Mobile stations in high-tier personal communication systems (PCS) are intended for high-mobility users and must thus operate in fast-changing environments. The first generation of high-tier PCS in North-America will be based on existing digital cellular standards including IS-136 TDMA. Moreover dual-band receivers will be needed for extensive roaming. Adaptive equalizers were devised for IS-54/IS-136 at 800 MHz. Achieving similar performance at 1.9 GHz, however, represents a new challenge because of the increased Doppler shifts. We present a robust MISE receiver with per-survivor-processing (PSP) which meets the TIA requirements in both bands and is scalable in terms of performance versus complexity.
