1 Overview ZXMW-PR10 is PDH family of digital microwave systems by ZTE Corporation. It leads the market in technology innovation, network flexibility, and IP evolution.

ZXMW-PR10 is a versatile, compact split type radio system. It supports both data and voice transmission, typically in mobile RAN, backhaul, enterprise, government, and public safety networks. It is optimized for combined PDH-IP operation in next generation wireless networks.

ZXMW-PR10 PDH supports frequency bands from 7 to 38 GHz and supports 32xE1 telephony or 16xE1 telephony with 4x10/100Base-T data interfaces. Software selectable QPSK or 16QAM modulation provides bandwidth range from 3.5 to 28MHz for 4E1 to 32E1. ZXMW-PR10 is developed for low-to-medium capacity PDH access and transport.

1.1 Key Features This section introduces the key features of ZXMW-PR10 microwave systems. The main frequency bands, capacity, modulation and capacity are listed in Table 1 .

1.2 Advanced Technology The following advanced technologies are used in ZXMW-PR10 Digital microwave system design.

1.2.1 FEC-Seed Solomon Technology

ZXMW-PR10 PDH System adopts twice accessional FEC coding technology. To build (252, 236) RS coding which is first FEC coding, 16 byte RS code was tacked after 236 byte. This is known as RS coding External code. The second accessional FEC coding adopts Convolution Coder. This is known as Convolution Coder Internal code. Based on this design, ZXMW-PR10 PDH System gets more system gain with less coding length.

1.2.2 Time Domain Equalizer Technology

In ZXMW-PR10 PDH system, time-domain equalizer consists of two parts, a Feed Forward section and Decision Feedback section. The Feed Forward section is a 24-tap, fractionally-spaced FIR filter. The filter coefficients can be driven by a blind CMA algorithm during acquisition or by a decision directed algorithm once carrier lock is achieved. A 3-tap decision feedback filter is used within the carrier recovery loop to correct strong minimum-phase distortions.



2 Product Description

2.1 Physical Description The ZXMW-PR10 PDH radio system consists of IDU (Indoor Unit) and ODU (Outdoor Unit). The IDU can be mounted in the standard 19” (483 mm) rack occupying 1U space both for unprotected and 1+1 protected configuration. The ODU is weatherproof and can be mounted in separate or direct mode with antenna.
